I use Deidara a lot! Also there is no 'spammer character' in this series (other than maaaaaybe PTS Tenten back in Generations whose every move was broken) because characters like Deidara, Temari and Utakata despite their bad reputation are totally fair. Their combos ARE their shuriken so they're very accessible and fair play, it's only when you do nothing BUT overuse shuriken that you are playing cheaply. Deidara has a fun awakening and a great tilt and jutsu. Plus nobody expects you to get up close and personal with his quick but short combos so you have the advantage there.Yeah I have ps3. As for Deidara, I simply don't you use him because I find him a very cheap spammer. As for Nagato, I don't use him like that. But rather wait to catch him at some point off guard, it's not like I use my chakra like that XD Also, in the beginning I first summon, whatever the case might be, Madara in order to uuse his fire so my opponent can't see from where I attack so and at that moment I instantly use awakening to shoot him while he still can't see. As for Shino I used to use him as well at some point but the problem is that his jutsu loses all its wrath once the opponent goes back enough.
Shuriken, like combos and everything else in the game- is good in moderation.
(also for Shino try adding another shino into your supports for the full jutsu effect, it's not good on its' own and you should rely on shuriken/tilt/grab and that stall awakening jutsu. The jutsu isn't good offensively, it's more of a- corner your opponent and overwhelm them jutsu.
