I've edited the lead post above. The FX of Combat Alert and Reflective Emanation (on minions) are now restored to their vanilla designs. Dmitriy ran a fix on the game's renderer that allowed us to use these FX without having a drop in FPS. Purists rejoice, the vanilla FX are back in use, and no longer cause performance to suffer! In fact all buffs that were previously causing FPS drops should now play much smoother.
