Meh. I rag on CO when I'm on it if I feel like I have a legitimate criticism to air. Like not understanding its tanking mechanics. (And this comes from someone who had an Uncrushable Paladin tank in WoW, back when "uncrushable" was a thing you needed to know in order to tank in WoW, and it wasn't even a term ever used in-game.)
I've tried CO twice before, and now that it's the closest thing I've got to a "fix," I find myself begrudgingly giving it another go, but I'm constantly reminded why it never took in the first place, and a lot of that has to do with a massively unintuitive design. It does some things really right, and it does some things really, really wrong, and I am not shy about pointing out which is which.
But that's the Vigilante in me talking, I guess.
