I've never played the NUN games (but I've pre-ordered storm) but in Clash of ninja my strongest character is Tenten. I hop into a corner and as soon as the match begins i jump and stick my opponent full of shuriken. The problem with this is that in NUNS shuriken do pathetic damage and you can't do much damage. Yeah they've nerfed tenten's best strategy; unless they up her power with shuriken.
if you were to use shuriken ALOT I would be very VERY* mad....and I would have to open not only 1..but two can of whoop * on your *
