Guild Wars 2

I really like you point – Traps should be devastatingly powerful, as they need some kind of preparation for fights, what should pay off once the real fight starts. Stacking Traps onto each other to nuke down the unlucky enemies that step on them is actually not possible – a condition remove and you’re done. Trapping was already back in GW1 one of my favorites, where it actually did damage. As any good player will probably run with some kind of condition removal, i feel like it got really inefficient by now.. Seems like everybody has to run Ghost Build haha

Viridi.5467:

If I play any other class, and I come across a ranger with the spirit-build, I almost automatically lose. They just CANNOT die, and if you magically manage to down them somehow, a.k.a. through the help of a teammate or trebuchets etc, they can summon their elite spirit right before going down just to get back up again before you can finish him.

I agree at some point. Spirits need a nerf imo – as a Spirit Build needs only a very low amount of Skill or attention to be effective. Condition / Burst Ranger Builds are pretty effective too, with a much higher Skill level needed to really change the outcome of a game.
I’d suggest lowering the range for the Ghosts effect a little with maybe some downgrades on the chance of triggering effects.
