it is about choice. If the energy mech it is giving you a better result in campaign, then go for it. Campaign will be your gold maker in 1V1 OD6 Insane. If energy work better, then use it. Energy mech at low rank can work too but require modules to support.
The energy mech built by Stormrider it is a decent one. You can copy that if have the parts. It will take you to some ranks like R10+ and use then the LVP. If you use LVP then will have to cover a bit heat module.
I decided to make this old mech I tested long ago. Look the replay. I played as dummy so you can see what side weapons and issue with drone plus the issue of the smart bomb with that energy available can do or not.
Pay attention carefully then tell me the issues. Of course, can work some. Look the power of my opponents and check the loop of players the game set me up for the loss. Even I played as dummy, the game wanted to screw me over.
Hey Oki Doki, I noticed that with campaign its really easy to energy break the bots so they can't use their weapon but it is much harder for me to overheat the opponents in campaign. Do I continue to upgrade my heat mech as my first one?
