There are multiple issues preventing me from using the hacking play-style:

1) Bots will not follow you through stairs/teleports/whatever. Not that huge of a problem if not for the next issue.

2) Hacked bots will be reprogrammed (and possibly kill friendly NPCs) if you leave their level for more than 10 minutes. This should be an easy change.

3) Going through the dialogs system to heal the bot takes too much time when you have more than a few bots assisting you. There could be a heal bot skill that uses circuits. Or perhaps applying the wrench on them should heal them.

4) I had to go through the dialogs to set each bot to follow me. There seems to be no way to set that as default. Perhaps another more skills could be added "broadcast follow me"  "broadcast hold position" "broadcast roam freely".

5) Invisibility is overpowered. You can just go bash bots freely with no retribution. I propose that bots be made to "see you" as soon as you attack them.

6) Skills are overpowered and bot damage under-powered. Especially late-game, when you have a 100-150 dps laser, 60 armor and all the bots have is 20 dps exterminator or twin laser.With exception of the forest harvester, their HPs are also very low.
