Yeah if you run sentry or anything that can be destroyed with a EMP grenade then trophy is the way to go. However, I have noticed that sometimes someone will throw an EMP grenade and my trophy system was on his lunch break or something. Destroyed them
both at the same time.
No problem. My blackhat LOVES taking out Sentry guns - through walls or even from the floor below. And surprisingly enough, a LOT of people run black hat. And don't forget that the trophy system conks out after 2 destroyed projectiles.
A Trophy System & EMP grenade cancel each other out (1 for 1 instead of 1 for 2). Also with the range on the EMP grenade, I can still take out both the Trophy System & the Sentry Gun without getting it anywhere near the TS.
