One crit to rule them all is the biggest problem. That needs to be fixed, then let trics sit for 3 months and see where they are.
In the short term, what if DPB spread out way more? So that the entire batch would be unlikely to hit the same target, or if it did there would be a delay since there's still travel time. After the first one hits you even a half a second is enough to pop an aoe or stomp on the gas until you can manually target the rest of its friends. This would also leave the option for cubes and gates to still be targeted with the entire pattern since they're huge.
Not a perfect solution, but it could lessen the chances of an entire cluster hitting a player.
