I do hope they:
-remove hit and weapon skills.
-optimize flying paths.
-remove spell ranks. I don't mind learning new stuff from trainers, I actually miss this. but fucking ranks? come on. it's not showing how you're a pro by using lower rank spells, it's a mana regeneration problem. problems either solved or bring new problems if left alone.
-use the new talent system instead of the old 'trees'. yes, both could be googled for 'the best', but balancing trees vs balancing new diablo-like talents?
-yes, I hope they will make boomkins and prot pallys playable. with old talent trees out of the way it's pretty doable.
-make professions relevant.
-increase stack size for mats.
-keep the 'questhelper' and 'atlas'. leaving people to search stuff online is just cruel. back in the day we did it, we hated it. come on.
-balance PVE/PVP items. no more poly-pyro.
-remove 14 dots per mob.
...I bet you can finish the list by yourself now.
and won't touch:
-using potions on CDs
-traveling to the other side of the world and summoning lazy asses.
-WSG, AB, AV.
-lockpick/poison leveling. because rogues must suffer.
I don't think I'm asking for too much. 99% of the stuff is in the game already. they'll just need to do liposuction and a boob job. that's it.
the 'vanilla' as we remember it is way past its best before date. if they roll it out without changes it will be like maintaining a nursing home from 19th century.
