EC needs a very slight tweaking Sackboy is fine, he actually has to put in work for good results, although he can be hard to deal with depending on the character you are using. Nariko is fine. Add BD and Dan to the buff list
Raiden and Coles are still hella dangerous. They can hit confirm off of some stupid stuff.
Ratchet can be annoying but the cornerstone of his game is his grab which is punishable. Though he does have really good ranged tools. FP is really good, but not broken. She can air camp way too well though but yeah.
