Depends on the sort of in-game activities you want to do. Some specs have more abilities, some have less, but for activities such as leveling, open world content, normal dungeons, non ranked pvp, you will likely do fine with your simple 4-5 spell rotation, 1-2 heals and saves, 1-2 interrupts, some mobility boost abilities, and that’s it.
You don’t have to think much about positioning, mobs have very simple mechanics, and you will rarely die. You aren’t punished for building a bad talent tree. You can do just fine.
And this is where one of the problems of getting into the end game occurs. Turns out many of the spells you haven’t touched at all, now suddenly require you to use them. For example, as a new warlock player, I never used the teleport spell during levelling, I didn’t care much about controlling who my demon is targeting, i never bothered using soulstone or thinking about the efficiency of my rotation. I survived just fine. I never required to look for a 3rd player to do any wanted quest, it specifically says that 3 are recommended, but me and my wife could kill any such mob with just the two of us easily.
I don’t know many other popular games where you have to actively read guides about how to play your class efficiently, and because of class balancing that can change every month, where last month your spec was great, this month it has become garbage and some talents have been removed and others added, it can be hard to follow. On top of that you are kind of forced in to downloading and setting up addons that help you play the game.
From that comes the large gap between veteran players and new players. A new player joins a dungeon, he isn’t allowed to have time to analyze anything that’s happening, the dungeon is just rushed through in the most efficient way possible, and if god forbid you pull a pack of mobs that weren’t supposed to be aggroed per the specific “efficient run/through meta of this dungeon” you will either be called out in the chat or even kicked. It can become a pretty anxious and bad experience. Sometimes the dungeon leader will lead the team through a dangerous shortcut, you can fall and die or pull a whole bunch of mobs you are not supposed to if you have no experience in how to manoeuvre this shortcut. And this is just about the damage role, but what if the spec you have been levelling is a healer or a tank, if you are new, you will suck and if you suck, it’s much easier to unwillingly sabotage the whole run as a new tank or healer player than a dps player.
And I can understand the mindset of the veteran player - they just want to get their loot from this dungeon they have been doing for the hundredth time, they don’t want to waste their time and wait on somebody, but this attitude is not good for the overall longevity of the game we love. It pushes new player away, snd without those the game will die.
There is a reason wow is not popular in e-sports despite having a sizable playerbase. Each class has so many abilities, the enemy has the same amount of abilities, so much is going on, it is incomprehensible and therefore not interesting to watch. I played league for a month back in 2014, and just after a month of playing a moba for the first time in my life, i could understand and enjoy the world championship. I have been playing for 9 months almost daily now, mostly pvp, and I can’t understand wth is going on when i tried watching last awc.
Anyways, i wish there was some sort of mentorship system in random dungeon and raid finder where a veteran player who passes some sort of dungeon and raid experience criteria is automatically put in as leader of the random dungeon and raid in is somehow rewarded by blizzard if the other players give him some sort of positive rating based on how well he interacted and helped the group through the instance. The reward can be some unique gear or cosmetic tabard or cape. There are games that have these sort of systems implemented, with various results, but it’s worth a try. Like a title “community mentor”, they won’t have any special powers like it was with the gm’s just simple transmogs and a title.
Oh and i almost forgot to add - no other game genre requires so many keybinds. I can’t imagine playing without my 12 sidebutton mmo mouse that has additional left and right scroll wheel clicks on top of all that.
Most people’s hands will feel comfortable enough on a wasd position, binding something on 1-5, f1-f4x q,e, c, r f, v, but more than that and it’s hard on your hands. I don’t remember my fingers hurting that much when i learned to stretch them for learning guitar chords, however, however i am still unable to press shift or ctrl key as modifiers for additional binds, so i had to bind 2 of my mmo mouse side buttons to shift and ctrl for that.
