Looking for help with barb build.

im running a 6IK 4 Reakor charge bolder toss build but sometimes i see it not tossing boulder toss and staying at max fury. is there a way to make it auto cast sprint then boulder toss when it hits max fury? i see in trinity setting under barbarian it have bolder toss / ancient spear delay time. should iset this to 0.000 ? i don't want to break anything thanks in advance i will edit this with some screenshots on of my current set up

also why does the bot sometimes not just zerg the rift guardian when he comes out it will sometimes go almost 3-4 screens away if mobs are still around. itll just F.C. over and over away from the RG itll only then fight the RG when nothing is around him
