I hate cloaked Flashes, and getting run down, etc.

Ours. DARPA is experimenting with such a technology as we speak. In fact, it would be better than what is in-game--absolutely perfect invisibility, even when sprinting in broad daylight.

Something like this, possibly:

nice vids ..i agree ..composite is in an' underestimated state. i myself explored the nfi-2000 turbo (atm r3), vehicle stealth (atm r3) , surger chassis (r3) & engi or ha with ai-at lockon (switching seat 1&2 (ok not new but still underperformed like the use of composite armor)) combo on my flash 3 days ago , there's a lot of potential inside & tons of fun.

I can see it being able to kill infantry but running over a max is a little far fetched !!

I find the wraith module on the flash is quite overpowered because of its capability to run over infantry while remaining cloaked and its ability to deliver explosives to sunderers unnoticed.

Spotting wraith flashes is incredibly difficult even with the sound because they keep the same level of invisibility regardless of their speed. This makes it so that even if you hear it coming, it is overly difficult to defend against, especially in busy fights with lots of infantry. On top of even trying to see the thing, actually landing hits on the driver is quite difficult unless it is driving straight at you.

The other incredibly cheap way to use wraith module is by grabbing an engineer with some tank mines or strapping some C4 to the front of the flash. I have used this tactic quite a few times and it gives the other side almost no chance to protect their sunderer. Same can be done against moving tanks as a way to kill them without them having a chance at fighting back.

Both cases are cheap and frustrating to be killed by because they offer very little in the way of counter-play, and the counter to it requires much much more skill or dumb luck than the tactic.
