I remember before Pre-OC I pissed off a bunch of people using a C4 DEF Nether. But, hot damn the ATK was terrible. The penalty on ATK really made it pretty bad.
I hope Nek0 remembers. He said it was annoying.
I did. Though I've never doubted that Nether was bad either. It just takes a lot of skills to play it really well. But to be honest, for that game, it was more due to the fortress than the gameplay of Nether itself. I had not personally met those legendary Nethers that can slowly disable you to death with the melee.
To me, you can argue that all MS can be played to some extent. I agree. But some MS are really comparatively poor to their superior counterparts, to the extend where you wonder, why the hell do I even want to play X when I have Y?
Take GP01 for example. Who honestly will give it a shit, other than the fact that it is the key unit for some suits?
