As a quick question, I'm doing the "Allies Under Attack" scenario (where you defend the Eridani, Grey Spire, and Shattered Pillar against Sorrow's Fang and Neinzul Astrids). I decided to upgrade the slicer drones for the scenario, thinking they'd be a good all-around unit. However, most of them seem to be plain stupid --- they decide to go after the bases rather than the actual units spawned from them. In particular, they target the Astrid bases, even though their champion is closer to the Shattered Pillar side. So not only do they have next to no health when they get where they want to go, they would get slaughtered by the bases regardless.
Not the most useful unlock choice, IMO. Is this normal? Possibly they pick their target when they spawn, and there aren't enough ships --- some do seem to attack the ships, though I'd estimate 90% of the time it's just they passed through it on the way to their doom. But even still, why pick something the furtherest away?
Or are they just playing Ride of the Valkyries too loud [1] to make sound tactical decisions?
[1]: Alternatively, they watched LEEEERROOOYYYYY JJEEEEEENNNNNKKIIIIINNNNSSSS and thought "BEST. PLAN. EVER."
edit: They will attack ships that are in spitting distance when they spawn, but after those are dead, they still strap on their helmets and "CHARGE!" passing by other perfectly good ships along the way.
