Now this raises a bigger question. Is Taric doomed to a life of an Auradin with Aegis, starks, soul shroud or are there other viable builds for higher level play?
I haven't seen a sucessful Attack power build(I'm not saying there isn't one, I just havn't seen or played against one), but I have seen multiple version of him. The best ones I've seen work against the composition of the opposing team, rather than a cookie cutter build.
For example, in a match with 3 burst DPS mages, I saw one carry their team to victory buy buying MR (banshee's veil for instance).
The aura thing is a good team buffer, but not a necessity. I usually don't like having one person in a group with all the auras, just because if they burn them down, you lose it. A good team will usually have everyone buying their own team auras.
Since he's a tank, it's important to keep an eye and know your enemies. Actually, that's the same for anyone. Learning to build against an enemy.
