well in my opinion is with earth one because u can boost him with shield and up them attack with earth main passive and with earth main u have a debuff remove aswell+ double attack (standart)

If your usual enemies are root of warrior/flower guard lineups or annoying sb with 4th mystery lineups then the best main is azure fang, otherwise is crimson fist.

Earth

Well for me, the best main for running 3rd ay raikage is firemain .. been using that main since i got 3rd raikage, earth main seems meh for me .. reason for me is when you faced and got matched with someone with 2 control ninjas like LightningMain-Sealing Slash with Masked Man, earth main can be shutdown fast .. while having firemain, you can reflect the first debuff and use 4th mystery to make your entire team immune, ofcourse except from masked man so it's a matter on how and when you'll use your skills ..

wind main for me, skill refreshing is OP!

Earth or Wind, problem with earth is mostly what Qv is saying but the buffs he gives to the team are just dammm, you can kinda counter that with having good init on samui to stop lightning main (with that skill he is not usually first position), with masked man there is nothing to do, but thats just why masked man is one of the best ninjas out there. Wind for the skill refreshing, Ay skill countdown is way 2 much in some battles but i still suggest earth, i was able to jump to six path rank on arena and not even with darui, i did it with omoi.

Omoi is much better than Darui in my opinion .. Most of my battles, Omoi brings the cake :D ..

the issue of omoi is that you have no control on who he will target with his standard attacks, and if ay and samui didn't start a combo it's a real issue, overall if he targets some ninjas like roshi or 6 tails.

Yeah bro, i do agree with that, that's Omoi's negative part ..
