What, people who like something else than you? Quel horreur! You must be a quite sad person if you're bothered by the fact that I'll never turn War Mode off because I want to find other people who want World PvP.
OT: I've turned it off a few times because there were WQs that were bugged in War Mode for some reason, other than that I've had it on permanently since it came, and I've gotten 350 kills on my allied race character I leveled for BfA, all in open world. It's been pretty dead at times, sadly, but other times it's been great.
