Here is my Taric Guide and i hope that it will help you a lot. In my opinion he could be a good jungler and i play with him many times. He mostly being played as supp but in S3 there is a new meta. He doesn 't need skillshot and he can be easily played.

Perfections

-Fantastic Ganks with a long duration hard stun
-Amazing team utility with his Q, W, and R
-Often underestimated, due to his commonality as Support
-Very good tank after mid-game untill the end.
-Supportive jungler who can help his teammates extremely good

Cons:

-Rather slow
-Fairly item dependant
-High cooldowns
-Once his abilities are burnt, he feels a lot less strong

Smite

As a Jungler, Taric needs Smite . Simple as that. There's no reason you shouldn't take Smite, and if you don't, you better not be playing in the Jungle.

Flash

Furthermore you would need Flash .With Flash you could engage battles or make easy ganks by flash and the combo E-R-W. Also of course you can escape easily from your opponents. At last but not least you could make some plays like steal a baron / dragon.

First up, his new and improved passive, Gemcraft. 2% of his maximum mana is converted into Bonus Magic Damage. This is quite nice, as many Armor items grant Mana as well, and means building extra mana greatly improves his autoattacks. It synergizes with Manamune incredibly well too. The damage is also doubled against champions!

Next up is his Q, Imbue. This is Taric's fantastic utility spell, granted a massive heal to one target, and healing Taric as well, unless self-cast. This item is really excelent for sustain, but the Mana Cost gets pretty high, so I usually rank this up second. It scales off AP.

Up next is his W, Shatter. This is Taric's main skill, and will be the first skill we max as Taric. It has an incredible amount of power, scaling off both AP and Armor. Passively, Taric gains a high chunk of bonus armor, and grants everyone else an additional 12% of his total armor. Activating this skill deals a high chunk of damage, and decrease their armor by a nice chunk for 4 seconds. This skill deals tons of damage when armor and AP is bought, and furthermore, the armor reduction means Taric's autoattacks do even more. He does lose his personal armor bonus too, but often this matters less.

Taric's third skill is Dazzle, his E. Dazzle is a decent duration stun, which deals more damage the closer you are. It's not huge damage either, but can be pretty nasty at higher ranks with lots of AP. This skill is Taric's main ganking tool, and the hard stun is really useful. However, I rank this last, as the damage is most variable, and feels less useful, though if you're looking for a longer stun, feel free to rank this up.

Finally, Radiance is Taric's ultimate ability, and is more utility based. It deals some burst damage scaling off AP, similar to Shatter, but also grants a nice chunk of AD and AP for 10 seconds, half of that to your nearby allies. It has a fairly short cooldown, so is worth using often.
