Recon C4 adjustment

There are some issues with the current C4 iteration that makes them simply more frustrating than rewarding, even when applied "properly" in gameplay as a close range threat to vehicles, namely:

C4 detonate sequentially:

that itself isn't a problem, the issue with it is that C4 disappears upon death, as any other bullet/gadget. I know this is done to prevent someone from spawning in and detonating C4 placed somewhere else, but right now due to the sequential explosion, it makes it so if u detonate the C4 on a tank, and u die midway, which due to the fast TTK of the tank, or people spawning, or general fast TTk, is very common, the explosions just stop and disappear, leading the player to slightly damage the tank, after taking the enormous toll of approaching the tank without dying, placing C4 on it and detonating it

Other issue is C4 interaction with the Reinforced Plating equipment on tank.

Reinforced Plating effectively raises the tank maximum HP, which leads to the C4s not eliminating them, and consequently leads to more frustrations and feeling of inconsistency of it. This could be solved by simply adding one more starting C4 for recon, although I'd rather have C4 ignore the reinforced plating as placing 3 already is a hard task.
