Not to be a nerfherder, but...
I asked this on the US boards.
Apparently on large teams the amount of PROCcing PGT did was nuts, 1 AOE check per enemy affected. So in a group of 10 every enemy would take on average 2 (assuming 20% proc rate) lots of damage from just one PROC being slotted.
VG on the other hand does 4 single target checks (single target holds) every few seconds. It isn't close to the amount that Traps did (not that I ever managed to check out a procced PGT), it's more like about 1 proc affecting someone every 6 seconds or so.
Ah, my mistake then. I've always thought VG also spawns one entity per target affected in the AoE.
Yeah, dual-procced Poison Trap nuke was insane against large mobs. To top it off, the two slottable damage procs were psionic, too. The fix was quite predictable, and perfectly justified. Poison Trap was not meant to be a damage power.
Would be nice if they upped the hold chance and duration though after the change so it's a brief control power again, though... but really, Seeker Drones and Caltrops are still very good mitigation tools used right in /Traps, anyway.
Edit: Only thing I really miss is aesthetic though, the impenetrable green cloud upon detonation in a large mob... Ah well.
The Poison Trap from the Traps powerset (Corruptors and Masterminds) was deemed too powerful and changed from spawning one Hold cloud per entity near it upon activation, to only spawning one cloud, period. I didn't get my own Traps high enough before the nerfbat fell, but I hear it used to be a "proc-nuke" as well, in that each cloud rolled seperate proc checks.
But... Why is it okay for Volcanic Gasses to remain as it is, then? As far as I know (I could always be mistaken), it works about the same way Poison Trap used to work, minus the Vomit check and -regen/-recharge. Couldn't it also be used as a proc-nuke?
Or is it just because it's in a Control primary?
Just curious here, that's all. Not intended to be a nerfherding thread or a Poison Trap whine thread - my Bots/Traps MM was in his 20s or so when it happened, so I've been thinking of it primarily as a -regen power from then on.
