Keep seeing builds with Lightning Arc in place of Tactical Missiles for single target damage. I really dont think the extra damage is there. First off Lightning Arc at least with my build is 300-600 damage while my Tactical Missiles are 430 a tap both are the same energy and both hit every .5s. Avg wise they both do the same damage Lightning Arc coming out a touch on top depending on crits. But the thing I dont get is yea you can Lightning Arc and Mini gun but I can Tactical Missile+mini gun+chest rockets(which add 700 damage a second(350 .5s) so Mini-Gun+300-600 damage every .5 seconds or Mini-Gun+430+350=780 every .5 seconds. Only downside I see is power use which can be fixed with most builds.
