I don't think anything disrupts the game and is as seriously overpowered as C4. It clears rooms, it destroys vehicles, it kills structures, it is basically and end-all be-all for absolutely everything. The worst part is that if you spend 450 nanites worth of resources on a large tank it is taken out by 150 nanites worth of consumables. Not to mention that unless your vehicle is spec'd out for infantry the best option is to hop out of your ARMORED WAR MACHINE and shoot the enemy with your gun. Its completely unfair and makes tanks feel like cardboard. And don't even get me started on how strong splash damage is in situations like holding a point or building. I only have a few suggestions to make it feel just a bit more fair. C4 must either have reduced damage of improved cost. There's no reason an LA should be able to ambusher onto a vehicle and in virtually a second destroy it. If they can then it needs to -cost-. I'm talking a single brick of C4 should be 150 nanites cost. C4 should be a "use it wisely" vs what feels like a spammable triggered grenade. That and honestly the factions should all have their own respective splash damage types. VS is obviously the Lasher type, TR is incendiary, and NC should be good ol fashioned explosives. With other splash damage effects and options, and C4 being more expensiveu, sing C4 as a room cleaned would be less incentivized. That way it fulfills it's job best as an anti-vehicle mechanic than an anti-room mechanic. That, and I do feel that tanks should take 80% of their current damage from c4 bricks without the flanker armor. It should be a C4 to soften, then two or three full magazines of rocklet.
