So, in BS, some units (i.e., capital ships) are worth more than one casualty. Having just shot up about a dozen Overseers, it seems to me that HS could benefit from the same idea. Perhaps a Collector/Assault could be 1, a Guardian 2, and an Overseer 5. Or something like that. Because it's definitely not worth the effort to kill an Overseer for the 450xp...

True roguelazer.

Eventually I would also like to see the combat xp and payment varying according to bot difficulty , and a wider selection of bots spawning in HS .

yes
