GG was always a strong super (in PVP) for its easy potential to get 3 kills. not many supers have a huge window to net 3 easy insta-kills, now do they? adding a 4th was simply just that: adding another easy insta-kill. now your total reward potential is squished into a smaller time-frame, making your timing more crucial.
are there any other exotics that directly buff a super as much as aclyophage does? especially in PVP?
it seems pretty balanced to me.
