So use lava burst proc, then use frost shock for 20% more damage on next lava burst. Sounds good, looks boring but a lot of the time I have a proc while I’m on global from frost shock. Id rather throw a lava burst for 100% more damage than FS for 20% more and be on global. I actually happens a lot.
In PvP between LB procs I’m setting up cc, being cc’d, kicking casts and using utility. FS is clunky and means lava burst has to do less damage because it exists, so now we have another global in our rotation aside from elemental, Prime, Ascendence, that’s not counting needing to juke or use utility to get someone off of you, and again the 20% buff and icy fury FS absolutely takes a lot of damage away from LB. It’s not hard it’s bloated, minimal visual and awkward. Pretty sure they couldn’t balance the damage of Lava Burst because of the RNG so they got lazy and made it not matter if it procs 60 times a minute.
TLDR Frost Shock should be utility and shouldn’t steal damage from Lava Burst and be another global for damage.
