Literally a bad idea to get feedback from these players. They main that class, most of what they suggested are buffs. I have yet to see any detrimental nerfs to their respective classes. They are all subjective when it comes to their own class.
Yes there are a lot of suggestions without proper explanations on how it would affect the balance like dreamer and others said. My main concern with turtle is their overwhelming crit damage. The "damage increased when critical hit is successful" lets a turtle 1 shot the majority of players. Would nerfing this mechanic be the right course of action as it is also affects classes like fighter. The team never promised to implement anyones suggestions. However im sure they would like to see yours if you even plan on contributing to this thread at all.
