Hi guys, I've played a guardian before, but I'm more interested in less responsible roles right now. I've always played a traditional tank class, but I think that I'm just more interested in solo play. At max level, I would be interested in raiding. Considering the above, which tank also has a fun combat rotation? I don't mind mixing in spells with melee combos, but I guess that I don't have a clear understanding of sk combat either. Please help!
As a tank you'll always be the responsible one. And for raiding as a tank you'd be expected to have top quality group gear as a minimum (imo) to be of any use. Having said all that, if you still want to be a tank, and solo is your thing, then any tank is fine. The higher dps ones will be slightly easier, SK, brawlers, zerker. But all are fine. You have put a TLP tag on the post title, not sure what that means. If it's TLE then SK is the best right now.
I guess that I like a more streamlined tank where most of the aggro, healing, or saves are either passives or built into the combat skills.
Then go zerker or sk. Zerk is very passive. Get hit and get aggro/healed. SK requires casting, but healing, dps and aggro is all combined in one. I don't know how far developed they are on the TLE though. I've played zerk, sk and brawler to 100. Never played Guardian or Pally to a reasonable level.
