I had a nice game moment where upon entering enemy area I found a powered down MadCat/Timberwolf just sitting there with the cockpit armor blown out, so I powered down my light mech (too poor to afford anything bigger that round) and jumped into the damaged Madcat and then successfully used it to sneak up on and kill another enemy Madcat, I then took the damaged MadCat back to base and repaired the cockpit armor and used it for the rest of the round... the balance actually seemed pretty good on it since it packs a large punch if you watch your heat and you can repair the cockpit damage by getting back to base.
