Guild Wars 2

Large groups of enemy players appearing out of nowhere on top of you doing damage before you can even see them, massive lag and frame rate drop to those without top of the line PC’s as well.
Is this fun? no…, is this fair? no.. Some may say this is strategy in a sense, but it really doesn’t function well, it exploits the weakness in the game engine and each persons individual PC, and I find it basically a built in cheat.

Now I am not exactly sure if this is a guild ability or Mesmer or what exactly, I just returned after being away from GW2 for some time, but I was disappointed to see this is still going on in WvW. It needs to be taken out of the game or reduced in the number of players that can use it.

Portal has 20 uses.
Mass invisibility targets limited amount of players (10 I think)
What they do is just stack up on one place and surprise you.
And about your PC… well they are always working on reducing the strain on your PC, but you can’t expect the impossible.
