I use it for zoning or to resuit. In most cases it gets 1 or 2 for me. If there's a chance to combo, sure, but I use it to help move a cart or gain a tick.
I don't understand people you do a multiple kill with ult in game and your mates go "DUDE THAT WAS HUGE GJ" you then proceed to show the same clip on this group and they go like "Press Q to win" wtf
