If you like to be powerful, you can do that.
If you like the idea of not being as powerful, you can do that too.
If you hate teaming, don't team. If you hate soloing, play an Ice/Empathy controller. (Kidding, mostly.)
If you hate IOs, don't use them. If you hate the incarnate stuff, don't do it.
Folks generally only get their feathers twisted when others try to push their "favored" playstyle-related ideals on others. Kind of like real life, in that way.
