Guild Wars 2

Like the title says there is a possibility to abuse a bug in the PvP lobby arena.
There are revenants that are attacking from the outside of the Arena by jumping in and porting back to safety

It’s not just revs. Any long-range skill, particularly those with 1500 range (i.e. rangers and engie mortars) works. These players hang on the corner and sidle in and out of combat and snipe off anyone below, ducking back when they are targeted. It essentially ruins the Arena as a fun place to brawl; if you’re not one of the vultures you’re dead meat.

just shoot em, pull em, or get close and wait for them to start shooting and not pay attention to gank.

I’ve seen ppl do this, I haven’t found they ruin the fun of the arena, also once we get people in the upper floor they are probably going to drop more annoying things in the arena.

DH F1 does the trick nicely.
