excuse me? what pvp? the endless honor farm? there's only casual PvP in classic if you want to use engineering and potions and all that crap in CASUAL pvp you still can do so in retail...
people complain about pruning in BfA and then proceed to claim classic is better /facepalm... i got to admitt that they're technically correct, they're not pruned if they never got implemented in the first place but... seriously?
for the record i main frost mage, go ahead and tell me how the ridiculous classic itteration that just spams frostbolts is 'harder' than the current one in BfA... ffs man you don't even have ice lance, not to mention flurry,frost ray, meteors, water elemental with it's freeze, ice nova, spell steal, frozen orb,ebon bolt, temporal shield...
i mean how do you even frost mage in classic? you're just a poly bot/frostbolt spammer that can use ice nova or ice block if in trouble, add cs and you've effectively have your 6 button class that includes dmg AND utility... even demon huntards have more buttons than that in retail... seriously count: meta+ 3 mobility skills+ 3 dmg skills+ interupt+stun + 2 defenives+dispel that's 11 buttons vs 8 on classic mage
not to mention that witout haste everything is like 15-25% slower...
well at least you got dampen magic and your trusty wand right? that must mean alot...
