Your feet are not nailed to the ground. If I run round a corner out of line of sight, YOU CAN MOVE TWO FEET FORWARDS TO STAY IN LINE OF SIGHT.
It is sometimes useful to whine about line of sight. In some fights, there are reasons why the healers can’t move - maybe they need to stay in range of someone else as well.
Or maybe the tank didn’t realise they could take a small step back and be back in line of sight. This happens a lot at the top of ramps.
For some reason characters in WoW are not able to target something that is just over the crest of a ramp when they are below it, even though they can see it perfectly well (this, in technical terms, means that they do have line of sight even if the game swears that they don’t. So annoying.)
But it drives me nuts when I’m doing a line of sight pull and the healer is standing there like a lemon while I’m luring some ranged mob around a corner. Of course I’m out of line of sight, that’s why it’s a line of sight pull. Do I really have to spend two minutes typing that before I do it, or … can I just assume that the healer is watching the tank. In a 5 man instance. Just before a pull. I mean, what the heck else were you watching?
Also, do not get pissed off at me if the conversation during the pull goes something like:
You: Argh … line of sight
Me: So move then.
Do not claim that this was not polite. Believe me, it was VERY polite.
