I have only three at max level
This char which is Resto Shaman (Necrolord)
Frost Mage (Venthyr)
Feral Druid (Night Fae)
I want to level my Paladin… which would be Kyrian… but its that which is holding me back… from what I have read, you have to do a dungeon as part of the Kyrian campaign which is not required by the others and don’t know if I can be bothered 
Shaman, DH, Hunt and Warrior are my four most played, also have Druid and Mage at lvl 60, the others are level 50.
At max level I have 6 characters, this one which is my main(nightfae) and then:
I also have 2 others at leveling stage, night fae druid and venthyr ret pally. I just do a couple wq’s with them every now and then, no hurry.
In BFA I played most DPS specs equally. Exception being Warrior and DH.
In SL I’ve been back and forth between Warlock, DK, and Hunter. Settled on Warlock for the past month though.
Leveled this Shaman first and didn’t like it. Have a 60 Druid too (funny because Shaman and Druid were the two I was struggling with on launch day to pick between) but they just collect dust now.
Generally I like a main and a complimentary yet different alt (or two).
E.g. Main my Warlock but have a DK alt, they’re similar (Pets, DoTs, etc.) but DK offers a melee experience.
Or my hunter because Warlock is slow, Hunter is mobile, yet they’re both ranged with pet and DoT capabilities.
I don’t enjoy doing the same content on my alts, I have my alts purely for PVP.
Currently I’m playing Priest, Warlock and Paladin.
I had every class at 120 in BfA, and the same will happen in a bit when my warrior and druid ding 60. But honestly, all I do is get a few legoes for each, conduits to epic quality, covenant armor with 190ish epic offpieces, and then just park them.
I’m too burnt out to be spamming 10 dungeons on each. I don’t have that much time nor willpower for it. The only one I put real work into is this priest, because she’s my main, but even with this, it’s a key and I call it a day.
69 of them
all because no content
Only 3 at the moment: Paladin tank, DH tank and Monk tank. 
Clearly I don’t like DPS or healing 
It’s surprising, but not bad at all 
I have Warlock, Priest, Warrior and Shaman with good gear and Mage, Paladin and Monk with bad gear.
But I have quit the game since a month back due to no interresting content and pvp being bad and neglected.
Currently dh, priest, hunter and druid. Warr and mage are past 50 but not yet 60.
I just see a big BLACK HOLE when dinging 60 on them…all the convent crap and torghast…not only gearing them up. … DH got 3 different covent done, druid 2 different convent done. Priest are on 2nd covenent but zero motivation to play the priest.
Currently 1.
Following a re-roll etc levelling all the other toons to 50 at the moment - got my levelling route down to about 8-10 hours without darkmoon faire, so hoping to get an approx 7 hour to 50 route this next darkmoon faire.
Waiting a bit longer before dragging those already at 50 up to 60 just to make sure they dont do any huge covenant shifts before i grind out renown to have to re-roll (covenant that is).
Next patch definitely going to play 2 - at moment contender is a prot pally and if i get into ret a healer - if i dont get into a ret a dps class.
Currently 3. A rogue, a blood DK and a holy priest.
Back in the days I used to play with my prot paladin as well, but it really doesn’t fit my playstyle since hand of the protector got a GCD, and they reworked SotR.
95%+ of my time in this game is spent on one character the one I keep up to date and raiding with. I don’t wanna play more than that, if I play to much I burn out and I prefer to enjoy my time in the game and by playing to keep several characters up the game will become more of a chore than acutal fun.
I do try other classes though but its just for fun and nothing I put alot of time into, most of them probably sits on between 16-24h’s played my DH got around 3 days played. If I ever reach a point where I really enjoy a class and spec more than my main I will consider rerolling to it.
But atm I feel that Paladin is the class for me, I got both Prot which is my main spec and the most fun tank spec in my opinion. I got Holy which is a spec I enjoy to play on the side and in PvP. I got Ret if I ever wanna dps even if thats not my scene I do play around with it from time to time.
Started with an Spriest but quickly found I was missing tanking
Did a paladin just to find out they are a bit gimped ( no added stam and takes a lot of damage , haven’t played since cata so big let down for me )
Now leveling a Druid for tanking
While I’ve also done a pvp arms wat cookie cutter for fun 
Been playing since vanilla, which I started as a Rogue. To this day, I’ve played every single class extensively – except for DH and DK, which I have no intention of playing at any point in time. Got videos throughout the years of me playing practically everything except the above-mentioned two.
I’ve swapped main-classes numerous times throughout the expansions and had never mained a Shaman, yet Shaman was what I always fell back on in terms of ‘fun alts’, so by the end of BFA, I decided that Shaman would be my main instead of the reliable sidekick.
At one point I was playing a total of 5 healers, 2 tanks and 1 DPS in BFA. In the present, I mostly rotate between four max-level characters and have no real desire to go beyond that. As it stands, one main for semi-serious play, two alts for when I want something different, and one final alt for if I’m truly bored enough to play it.
I have all classes, some even on both the horde and ally sides. The class I enjoy playing the most is priest.
I play 4 dk rogue hunter lock i had Every class in game but deletet the rest it is just no longer douable to play more than 4 in the current game.
Trying to learn to focus to play one class but it’s hard so I have one of each
