Hi, first of all it's a very old thread so you shouldn't get too much from this tier list, there has been lots of updates from versions to versions. Second it depends on where you are at in the game. Quote alvinpabesjr2699
How can Admiral be at S+? I always main him in my game and I hope to improve my skills with him, DH and maybe Unholy knight if I can master his playstyle.
If you play solo and you're struggling to kill death/byatis/icewolf or bosses before that I suggest you play a full dps build with a life steal and carapace armor objects maybe, then by getting holy bow not too late those bosses should be ok (Don't forget to use your items such as holy bow and/carapce armor after using your ultimate (I guess you know since it is you main)). The goal is too end fights in 12 second max. A good tip is also depending on your remaining time to not kill typhos and use him to cleave gaias by stunning both of them and hitting typhos with aoe spell. After forgotten one, kelthuzad and deathhood this play style doesn't really work anymore. I don't really have tips for solo play after that because you go further than me
If you play team games I strongly recommend watching games played by team hellfire in Quests (on the forum). It's usually more based on a tank build with holyarmor and crush damages
