THE SUGGESTED FIX:
WARNING: THIS THREAD HAS BEEN DERAILED
1: return pen shot to its origional 5 second cooldown
2: increase damage and/or armour penetration
3: add 2-3 other ways to spend focus regularly (ie on 5-10 sec cooldowns) .
(suggested types [pick 2-3]: large bleed shot, 5-7 second root shot, threat-down shot, aoe frontal spray shot, HoT shot, debuffing shot)
