At first: The Antimatter Drop itself needs a range scaling, 15m is just not good.
Secondly: The Ability is unplayable! After I shot the Drop it randomly accalerates, stays EXTREMELY SLOW until it finally hits a wall or simply takes SECONDS to explode, when it just sticks to a surface for 3-6 seconds. It is UNPLAYABLE in ANY mission and while I can understand that synchronising the drop for other players is difficult, this ability seems to be completely wrongly programmed in the first place. It is laggy, buggy, UNPREDICTABLE and simply put: UNBEARABLE !!
I have played nova in the past, years ago, for hundreds of hours probably. FIX HER BACK: Antimatter Drop Range scales with range MOD ! Simple! After shooting the orb it stays slow for 0.3-4 seconds, just enough for ONE FULL TIGRIS reload. Not more. The normal flight speed has to be INCREASED. Slightly though, from normal.
The core of this (my first ever report) is:
Completely re-code the Ability. It seems stuck in the past, while many other things are synched and move and work perfectly. This isn't one of them.
