MAXes are extremely overpowered in their current state. They should be nerfed so that once they die, they can't be revived.
One brick of c4, or some heavies that know what their doing (or one REALLY good heavy), and that max is down. You'd be surprised how easy it is to kill a max that over extends, even with small arms fire.
I could say the same about a tank. Except it would be 2 C4. Maxes need to be unrevivable to have any semblance of balance.
Sure, as long as you make them invulnerable to small arms fire and have weapons that one shot infantry like tanks.
In that case make MAX suits able to heal themselves effectively like a tank would. You can always climb out of a tank and repair.
MAXes in their current state are just superior infantry. They're for bads to feel like they're good. This will not change.
Or the MAX that can get close to the battle, has no real weaknesses other than what already kills normal infantry, and a typically larger ammunition pool. The NC MAX is the only one that fulfills a niche. The Vanu and TR ones are just infantry++.
