I play the only class with a damage-dealing ability that works differently in PvP. Colossus Smash is apparently so potent in PvP, entirely because yet again it’s reducing armor, that it has to function differently there. Now, in response to a forum thread asking why all spells aren’t balanced separately for PvP and PvE, Ghostcrawler responds.
It’s not our option of first resort because it’s not intuitive for players and it means anytime we want to make balance adjustments, we must change two sets of numbers.
This leads me to consider: Should it be more common for abilities to work differently in PvP and PvE? I’m sure we all agree that the other guys’ abilities should, but once I start mentioning an ability that you actually use in PvP, you may suddenly feel differently about it. I’m not going to pretend I loved the Colossus Smash change, but I understood why they did it.
