I don't have a list because I haven't played everything fully, but I can give you my thoughts on those classes but its strictly pve perspective
>Mage
Frost is decent actually compared to past iterations I don't find it as boring and there's a good mix of talents
Arcane is alright, mastery feels a bit weird to play with and it doesn't feel as good
Fire is pretty boring just because its a bit minimal, there's not a lot of depth to the rotation its mostly just whether or not you get procs, I guess it can be fun in dungeons where you get a really long proc chain and do big numbers
>Lock
Aff - pretty boring, noticeable improvement in its ability to actually do aoe though with seed of corruption, reminiscent of WoD AS shadow priest
Destro - decent fun with talents, not that fun on single target though, but with portals and havoc and everything there's enough to keep you engaged on multi
Demo - very divisive, its a lot of turreting just hardcasting shit, I personally don't like it but there are others who've told me its the best spec they've ever played
>Shaman
Ele- Actually not bad, with talents its pretty decent to play, and this is coming from someone who never really got into shamans
Enh - Good fun to play, not as spammy as WoD but nonetheless engaging
Resto - eh In my opinion slightly worse than WoD not really a lot there to play around with
>Druid
Boomy - engaging with the right talent setups and multitarget, a bit boring on single target because its just spamming alternate spells, but good depth
Feral - they didn't really fix its gaps but its playable and not too bad I'll have to wait and see though
Bear - boring as fugg desu
Resto-samey
