Captured a crazy bug on the roller beetle racing bubbles. I get complete freezes every 5-10 minutes, otherwise vastly improved performance.

It needs to copy https://wiki.guildwars2.com/wiki/Spatial_Surge mechanics except the beam should heal or give buffs to friends. That way it would still be single target but would have a very "Guardian" Flavor.
Honestly if you just reworked the AA it'd become popular overnight because it has great numbers and good utility. Make it a continuous beam or something like arced lightning.
