The Lord General is a lot of fun, but he seems awfully glitchy. His Bolter does next to no damage, his Grenade Launcher says it causes knockback but doesn't actually seem to do so in practice, and one of his heavy turrets often causes no damage whatsoever and damages the ground with every shot, which makes the game really laggy and often causes people with slower computers to lag out entirely. Worst of all though is his retreat ability, which sometimes cancels itself when the Lord General gets hit. So basically anytime you're retreating from something as opposed to just retreating because you enjoy the concept of being able to retreat you've only got about a 50/50 shot of actually having it work.
Amusingly, though, he usually defaults to attempting to melee the enemy that attacked him, leading to a scene of your General running away until he decides that actually, on second thought, he would much rather engage in a boxing match with that Carnifex that just took a swing at him.
It's actually kind of a cute way to die.
