Betrayal league went pretty well for me, i'll get my character and for the first time will continue playing it in standard.
For Synthesis, i think i'm gonna play a dual wand witch with the new chaos spell - looks awesome and i wonder what good supports are going to be useful for it.
EDIT: imho they're trying to make so triggered builds are more focused on endgame; usually the gear setup requires more effort for them, buidling around a single spell can be easier providing a better transition curve from inital levels to endgame.
