Nice overall guide, I dissagree with one thing though: You say that Gemcraft only restores a "small" amount... I don't know how you come to that conclusion, the way I see it, your ~100 AD * 1.0 AS * 7.5% = 7.5 Mana per second = 30 MReg/5 sec... Have you ever tried to get that much MReg with items ? Its a whole bunchof it even with only your base stats! And it may turn into a permanent blue buff if you increase your AS and AD even slightly with Radiance and Zeke's Herald or the like...

This site kinda needed a good jungle Taric guide, and you seem to be delivering on that front. Quite a nice start, though a lot can be added, like making the guide a bit prettier, jungle routes etc. One thing: Using Shatter does not disable the aura while on cooldown, contrary to popular belief. It disables Taric's own armor passive for the duration of the cooldown.

Good build overall, ill try it when some friends are online for a fun game :D but I do think that your role would overlap quite alot with the other support, even though you can build for a lategame tank of somesort. IDK why but it seems to me that you might be able to build him.... AP'ish?? don't know his ratio's on the top of my head but I can remember some good kills that I had playing him as a support, so add a couple 100 AP to that and it might become something quite deadly :) just an idea though... but nice build overall!

I'll list a few things I see is wrong, or has flaws.

1. The aura build only has one aura. (I'll assume you'll let the last slots be other aura items based on the comp)
2. The tank build has a warmog, which is by itself, not worth getting. Instead, a Randuin's Omen, or Banshee's Veil would be better and more efficient. Even an early GA to some extent, or if you want damage, a sunfire cape.
3. For your first aura build, you should have the 2 points in minion-damage reduce, as it lowers a lot more damage then you'd think over time.
4. You say Swiftness gives 4% movement speed, but in actuality it is only 2.

I know it is not finished yet, so I'll assume all these will be easily fixed/explained later on.

Great build so far, you have my support! I'll come in to check again when it is finished. +1
