The main problem is 1) shit pathfinding 2) small assist range.
It's same shit pathfinding and bad range at all tiers.
Kennels/hives fix both problems, kennels have worse bp but can fly anywhere.
Pathfiding is not fixable, but better range is changeable.
We need a way to contrate bp efficiently in specific area.
Deploy button on engineers
After deploy engineers cannot move and get double range effectively transforming into small hives
No pathfinding - no problem
