Guild Wars 2

Trap name : corrupted trap

Effect: when under the debuff of corrupted boons any boon trigger or already active will be flip to a random condition type and duration of the boon.

Might would only trigger bleed or torment. well all other boons would be random. meaning if you had 25 might have a 50-50 chance of it switching to 25 torment or bleed.

Corrupted boons Duration last 30 seconds(does not stack will not reapply till first effect is gone). Trap condition damage is based on player who set it.

Cap at 150 boons burst trap all player hit by the debuff have 10 chrages of corrupted boons on them for 30 seconds. meaning if htey use a boon well they have the charge on them they get flip to con dmg max hit is 20 players.

this idea is help counter against zerging : )

Cool Idea! have a +1 from me

I dont like traps, a lot of exploits and balance issues there.

Big zerg on zerg fight. Guardian pops stability and just places a trap in the middle of the enemy zerg.
Thief stealths and just places trap in the middle of enemy zerg (he can even teleport while crafting to be 1200 range away).

So they wont be used as traps. Just as a zerg on zerg weapon, or by Thieves trolling.
