Would you be willing to update this mod with compatabiltiy for LW Mecs as Sparks? I've tried the option below to add it manually, but I can't seem to get it to work on my end.

I believe so

Is it as simple as adding Template.AllowedClasses.AddItem('Insert Class Name Here') under the lines adding the abilities to the Spark class in the appropriate .uc file, or is it more complicated than that?

I am kind of nervous about altering anything, I'd rather not have anything just violently explode on me or something because I don't know what I'm doing.

It could potentially be done, if you know the class names from the other mods.

Is there any way to modify this to work together with the various extra SPARK class mods? I get why they don't already work together - the abilities added by this mod are only actually pointing at the original SPARK class and not the modded ones - but I don't know if that could be changed at all.

IIRC, the equivalent perk for MEC Troopers in EW was called "Damage Control"

Have you considered renaming regeneration to "Nanomachines" or "Automated Repair Protocol"? Makes more science fiction sense and sounds cooler! Great mod!

Is this compatible with Metal Over Flesh?

Not a mod I use, so not 100% certain, but I'm guessing there shouldn't be any overlap. This mod adds perks which apply to all of your sparks, vs individual abilities which are added via the other mod.

How does this interact with https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=1123345891 ? (Sparks being able to use the AP system)
