You’re good with any class. I’ve been doing them with all 13 classes, and they all feel fine. The only thing I sometimes find a bit annoying is some teleport attacks, like outlaw rogue’s killing spree, which can land you on web traps, etc. My fury warrior feels very strong, so I think you’ll do well with your warrior.
You should, as others have said, be fine on any class you can play reasonably well.
From personal experience Prot/Fury, Blood/Unholy, Prot/Ret, Frost /firemage, Guardian/Balance/fderaldruid , demo /afflock, MB/MM hunter, Devoker… all work just fine…
I do have to admit that they feael easiest on demolock and BM hunter, turn off brain and let brann and teh pets do most of ht work do the work… but I also have a level 60 brann set to healer…
I was doing them on my fury warrior that i think is at 616ilv or something, did zekvir on ?? And my fastest delve currently is a fungal folly with a sub 4 minute full clear.
I also had an easy time on all 3 mage specs, ret paladin and a DK so id say just pick whicher you feel comfortable playing.
Not had an issue on my fury warrior. Just set Brann to healer and lvl him up a bit and you are golden. Fungal Folly seems to be the quickest delve to do.
Warrior in good gear blows through delves like it’s nothing.
The spec doesn’t even matter at this point.
As a Prot, I can clear T9’s without breaking a sweat, haven’t tried the higher ones yet.
