Points to get 50% Energy Regen: 10 (also, the Super Robot Upgrade List needs to be fixed, the maths is still working out as if there was a fifth)
40% HP Regen: 10
Agility/Targeter/Plating/Mighty/Battery Maxed: Level+1
Points by level 3: 12. Two robots to supply regeneration, and one with, say, flight. The other takes one of the weapon upgrades. Two more spend four points each on agility/targeter/plating/battery, etc. At level 3, you have maxed HP, AC, energy, energy regen, HP regen, DR, speed, and flight. Now, the big expenditures for half your robots are out of the way, so you can have them choose weapon upgrades, or transformations, etc.
Hell, the bigger problem is that you run out of upgrade choices by about level 8 and have a perpetually maxed robot. With, as pointed out, high base stats as well.
