I believe so, wrath to cata had the talent point squish. While pvp players speak well of cata that isn’t what most players want and I believe people were put off by the lack of easy pugging. People would fight and argue over group setups, wrath grouping will be easier and for players with a 70 twink character, I believe that while retro level 70 guilds will be a thing at least on the megaservers, and it will be easier to math the groups without having to deal with who goes where, except for the 5 space goats.
in vanilla it was easier, a few tanks, put the mages and locks with the critchicken, a hunter in the melee group along with a feral druid, and maybe a paladin/shaman for resistance. The power rise was with world buffs, not stacking buff giving classes. In wrath buff giving classes are raid wide and if you use the exp eliminator at 70 you will get a probably better experience, it is like a good thing when you are in a group which gives you the buffs to do well, but when people didn’t have to worry about world-buffs they loved not raid logging, and when people don’t have to worry about fighting over the enhance/elemental shaman they will be more relaxed when group comp is a minor issue.
Like in classic one doesn’t have to worry about bringing 24 warriors because the dramatic increase in power is in world buffs, tbc it is in good raid comp, while wrath will have tbc but with raid wide buffs (and wrath 70 twinks) meaning we can probably have FREEEDOM from group wide buffs, which is what I look forward to wrath 70 twink raiding more than tbc era.
As for wrath being everyone’s favorite I think the interview said they would keep era but not likely do era tbc because the demand for era wrath and vanilla was higher.
