Why go with elemental relic when we do mostly kinetic/internal damage?
Because the developers put relics in the game without explaining their mechanics.
Some very goddam important details you need to know are:
1) The procs use your Crit Multiplier
2) The procs use your Crit Rating... but...
The hilariously not released information is that:
Kinetic & Internal use Tech Crit % (troopers and scoundrels)
Energy & Elemental use Force Crit % (consulars and knights)
Came to the conclusion in a thread on the commandos forum where kinetic would use our tech crit rate but elemental would crit for way waaaay less, 15% less on massive parses.
The reason? It's using the force crit rate which is much lower on a commando since ofc aim doesn't give anything to it.
