Isn't the boost from Shifta/Deband only applied to weapon ATP/Armor+Barrier DPF on Blue Burst/Ephinea, though? I've been kinda confused on whether they takes into account base + weapon / base + armor + barrier of they just uses weapon / armor + barrier on this server.
Regardless, I have to agree with Ade and the others: it would run the risk of being a bit broken in Solo, given the 100% freeze rate with Freeze traps, on top of everything else RAcast/RAcaseal have. At least HUcast and HUcaseal have the excuse of being primarily close-range DPS, and thus every hit that kills an enemy is a hit THEY won't take (while RAcast/RAcaseal can play keep-away and pick off foes, most of the time without being in any real harm).
