Guild Wars 2

I disagree… It has nothing to do with knowing the area, unless you mean memorizing the location and number of EVERY SINGLE MOB in the game.
When I enter a new area and see three drakes and start to attack one, how am I supposed to know that two are missing and that their respawn timer will put them beside me just as I’m almost winning but with low health and a heal on cooldown?

There’s not many things that I find annoying with the game, but this one ranges sky-high on the irritation-o-meter. I’m pretty sure many of you have encountered it too…
You’re out there killing various beasts when suddenly, right next to you, a new monster spawns… And instantly attacks you!

I understand that some mobs are flagged as agressive and some not (red and yellow name respectively), but would it be possible to add a timer of just a few seconds (3-5 should suffice) to newly spawned enemies before they start attacking?
That way I could possibly run out of their aggro-range, negating the problem entirely. It would also add some tactics to the battle: Do I run away while taking hits to not aggro the new arrival, or do I stay and face the wrath of them both.

Naturally, if the player hit them in any way all bets are off.
