In terms of pvp who in their right mind would ever use a High impact fusion when the faster charging ones can get the 1hk faster and more reliably? It's basically the 120 vs 140 Handcannons, ya the 120 does more damage and has slightly more range but why use that when the 140 can do it all and in most cases do it better. Even in pve, unless my 1000 charge time fusion is doing damage similar to 1k voices, (I'm talking it will straight nuke a champion in GMs in the seasons going forward) there is now reason for that ungodly charge time. Rapid fires and precision frames can clear mobs and DPS beefy enemies better in every way. The only exception for high impacts is a very specific roll (subsistence + reservoir burst) on a fusion you can only get once a year during the Christmas event and even then, that just for ad clear.

The op was upset with the charge time. I responded My response to you would be the same for your hand cannon example This whole game is monkey see monkey do

Throwing poo at each other would probably be more fun 😂
