Gaara shippuuden mystery is even stronger ;-P. That said, is not true at all that his damage is so op. You get a 5k on a crit if you have boosted him with bee, wind enhancement and the barrier is up and still, for example, in the same team sage naruto mystery do about 20% more damage. Tenten gnw with only the barrier of mei and water enhancement do the same 5k in round1 if doesn't crit. The same does a tendo boosted in an mb team with wb asuma and a 2nd booster.
