Well the arena queues predicted times are pretty accurate for me. I could queue up before engaging a boss I have trouble with and if it goes bad i'd have arena queue as a free escape. 'I could', as in people could. Going to arena entrance and then leaving straight away again. Every little trick gets exploited in this game, leading to annoyance for others.

But i do understand your point, a bit more flexibility wouldn't hurt. But it's like my mate in the guild: he dc's now and then in a bg: so until a week or 2 ago he would be booted from the bg and get deserted buff upon logging back in. Major anger towards blizzard from him. Now they've fixed this and they apparently gave players more time to join / reconnect after a dc, and now he is pissed when we have to start a WsG with 8-9 (1-2 guys who dc'd or did not accept the inv) and why they don't get kicked. So hard to do right for every situation.
