skirmishes should take a really long time but guards should do more damage to offset the fact that the infiltrators are able to not only stealth, but regenerate health
the idea being that the infiltrators would want to avoid direct combat, unless they have an opportunity to fight a single guard and peck away at the enemy force
also seriously anything that works like a spear is hella dumb. you should change the finger trap into a finger trap launcher, or have them work like T+T's grenades do in that you CAN hold them down, but have no real reason tom*
* this part is mostly personal preference because apparently people can, in fact, finger trap dudes and it seems to just be me who can't do it for stuff
