Being somewhat new to online gaming, I have a couple of questions about etiquette in....
1. When doing quests or just getting from A to B in the open world, is it acceptable / appropriate / polite to heal another player if you notice they're not doing so well in a fight?
2. Similar to #1, but swap "heal another player" with "attack another player's target" if they're not doing so well?
3. During the Open Beta, I was at the Magic Stump (or whatever it's called), I saw someone complaining about "queue jumpers" - can anybody elaborate on what that was most likely about?
