When i started playing this game in the server opening event they put a wheel with pain shurado and pain ningendo x30 frags.
It was amazing cause you would see many people getting their frags and eventualy almost everyone started with 1-2 pain in their lineups. Sure they're not endgame ninjas but that's my point. the ninjas featured in RNG wheels don't have necessarily need to be endgame ninjas with 000000000000000000,1% drop chance.
Would they put average decent ninjas like some kages, some christmas/summer ninjas.. lower frag amounts like 20-25 frags and higher % rates it would be so much better, in my humble opinion.
