They probably thought of the IB and sidearm issue before the patch was made. If they didn't fix it before the release then they won't in my opinion . As it would be basically making 1 weapon not an exotic and also making a special weapon type not work as intended. If they wanted to fix the trials properly then I think they should make it so either you can only have 1 exotic equipped all together for your character. Or no exotics at all. That would fix the biggest issue since I'm sure alot of people still enjoy having fast revive over having a under powered gun in trials.
