ok check this out here is a big dmg combo for pvp (only good if your rate is above 50%and have higher crit dmg of 200% or better) charge lvl 20, splinter lvl 18, break lvl 18, ray lvl 20, splinter lvl 18, (you can add another filler here if you need to make the loop to use another splinter) and as for pve stun-lock I found it better to use splinter lvl 9 and blades of justice lvl 9 only (at lvl 9 you can combo the 2 attacks forever as long as you reach 3/4 mark minimum on the combo meter each time you use a skill)
