This sentence is false. There is no requirement for any action in this game. Players consent to the terms of service/code of conduct and proceed to enjoy the game to the fullest extent of their imagination.
Sounds like your personal playstyle. Cool.
I don't even know why you're responding to this if you're saying is pedantry - like that is the definition of the word, that you would break down my entire post to point out minor things you disagree with?
Is this humor? I didn't laugh.
Cool. And telling people what roles are for, are for people who need to tell people how to play. Look I can do it too.
To the topic of the thread - the game is not balanced around IOs or damage procs, or set bonuses for that matter. If you want to play a certain way, such as using everything you can muster in the game to your advantage, go for it. If you don't, then that is your choice too. Only thing players are required to do is agree to the rules of the game and log in, after that point it comes down to subjectivity.
