Doesn't matter if leanson used a 400 mass ship or a 400k mass ship, the use of overdrive renders shields useless (since it's bugged as hell) and basically means that the first to spot the other instantly wins.
You can't justify the abuse of bugs to gain a superior advantage over your enemy. It's not called smart design, it's called being reliant on broken shit. Besides, if your ship engineering is so good, then why do you need use glitches in the first place? The way I see it, is that you'd get obliterated if didn't use bugged features and stayed on a leveled playing field.
I might be wrong about that last point. If that's the case, then prove it!
