Levelling to 50 at the minimum is a very easy process now.
The trouble is you only have on route for fast levelling some of the older zones just yield poor xp.
WoD for example. Upon hitting level 10, going to chromie and picking the WoD timeline I completed the intro and was already level 15/16?
I then built the garrison and began to quest, qued up for dungeons as I went.
By sixteen logged hours on my character I was level 44 and this was me taking it slow!
It is very easy to hit fifty within eight or nine hours if you maximise XP gains by doing WoD quests and que up for dungeons. Even as a DPS you’re probably looking at a comfortable 18 hours tops to ding, just over a days played to hit 60 as it currently stands.
This isn’t including timewalking dungeons of which two or three is a guranteed level, 50/60 is around 36/40 timewalking dungeons if that to ding max, though it’s just as quick, heck maybe even quicker to buy renown 60 and do the threads of fate now.
Levelling shouldn’t be instantaneously fast but…I do agree it shouldn’t be painfully slow either. It’s a journey I done in wrath then again on classic, one that whilst good fun, I don’t think suits modern gaming one bit.
The current time to 60 feels about right to me, not to fast, not to slow.
But plus one on the heirloom point, after spending the gold upgrading I felt royally stung after that change, even a 20% xp buff would help shuffle things along now.
I also feel like for every quest you complete you should get a burst of knowledge buff that increases kill xp by like 100% and quest xp by 50%.
Short enough that as long as you’ve cashed up four/five quests in the area you reap a nice benefit?
Or heck maybe even bonus xp from dungeons if you play tank or healer!
