I highly recommend using Field Mods to allow two completely different playstyles on the French lights and mediums. First, sr360s stealth build (CVS/optics/exhaust) is awesome for maps where vision is king (prok, mur, red, etc.) For all other maps, running a gunfighter build (vents/vertstab/improved accuracy) is amazing as it fixes the awful gun handling and allows tanks like the Batchat and 13-105 to do lots of damage, even at distance. For teal players like me, making tanks like the Batchat able to deliver clip damage with dispersion of just 0.32 or better is an eye opener.
Preliminary testing shows that the Progs 46 and 65 work pretty well with the Full Stealth meme builds. Is this heresy? I dunno - no one likes the Prog65 anymore anyways and I didn't like it even at peak power. The 2% camo that one gets at full field mod level pushes it's on the move camo to 40% aka the same value as the T-100 prior to this patch. With 527 VR and slotted CVS. And the ability to swap to turbo/vstab/vents for your Himmels and other no vision maps. It'll probably let me enjoy 3 marking them. I'll test the Prog65 more in Ranked tonight.
