Full engine kills destroy your mech.
Unlock Solaris specific decals and anything else they can think of.
A big part of Mechwarrior was the honour between pilots. Letting another mech limp off the battlefield or if they are a true enemy, step on their cockpit after downing their mech.
Plenty of lore supports that even during raids between Houses injured mechs were left unmolested to retreat, because you would want them to do the same if the situation were reversed.
The game lacks depth.
I've also always thought we should have pilots we slot into our mechs for slight bonuses. Your Solaris stable could have techs and engineers you slot in for whatever they grant.
