she has the basis of being an op character within the kunoichi but she was trolled, and example would be more complex function of her tools, poison in her tools agility and tactical use of tools, many factors could play in that would make her a splendid ninja.
Tenten is limited to using Ninja Tools, so I'm afraid it'll be difficult for her to surpass the other kunoichis.
Most shinobi (unless they're fodder) would be able to simply deflect or avoid shuriken/flails/explosives/etc.
<div class="bbWrapper">If she'd play a bit crazy engineer and make some grenade thrower or some op weapon she could be good.<br />
Right now she is only good in Generations,and even there she is overpowered by Temari and Hinata.... XD</div>
