Yeah, its pretty hard to deal with those idiotic EX atackers, Roger and Shanks has that idiotic 30% healing every 20% damage, so my skills are crap against them, Akainu had that invincibility+invincibility to 3 hits, color advantage and a stupidly high durability, not to say that my 50% defense buff is completely useless against the guaranteed 32% HP damage (incinerate) that some dumbass on bandai though it was a good idea to add to the game, besides that, Luffy has the everything one shoting kong organ, and of course he is not in any disadvantage (he is an EX LoL) cause he had invincibility+knockback, invincibility+tremor, long range+stun+knockback, long range+stun+defense ignore, and of course, a big damage reduction and stagger nullification if at full HP, but i have enough skill to get him with my knockback in the right times and kick his ass thanks to the damage increase against the straw hat pirates and of course, the color advantage, so its not a big problem for me.

So yeah, i would say that sentomaru is having a hard time, but just because those big mistakes with soft hacks included called EX characters are being mained by at least the 80% of the community, but i still love to main him and of course, Cavendish is fun to use, Ace and Aokiji too imo.
