So the game is now going to force a link of Steam and Arc. Do NOT go through with this. Find another way to play or don't play at all, because it's woefully broken.
1) It'll force you to do a complete patch of the whole game, no matter if you usually play through Steam or not. That takes a good long while, but isn't the worst part.
2) It'll wipe you account of all your toons. Simple as that, everything is now just gone on my account. No toons, no nothing. I only have this one account, I've been playing via Steam for months, and now everything has been wiped after the link. I even logged out and then in again, hoping (vainly as it were) that it was just that this link for some god forsaken reason created a new account for me and made sure to log in with my usual account. Nothing. Everything gone.
No idea what they screwed up, but they TRIBBLE this up royally. So do not go through with this.
Logic is the beginning of wisdom, not the end of it.
