Played a couple matches on the test server and this might actually be worth the 261k xp cost. Maybe it's just test server pubbies, but I did almost 3k dmg in my first game in it.
Pros:
-Good gun depression
-Decent camo
-415m base VR means that you can hit 460+ with a halfway decent crew
-Feels like a small Batchat
-27s base clip reload is comfortable
-Can mount a Vert. Stab (IIRC the French tiers 8 and 9 can too, not sure about the AMX 12t or the 13 75)
-Aimtime is less than interclip and I got mine down to around 2.16s
-Small size
Cons:
-Somewhat sluggish (high hp/ton but I'm guessing it's murdered by soft stats)
-Turns slowly (like many French high tiers)
-Limited clip potential
-High bloom even with a Vert stab.
I might be grinding this out on my account when it gets released, especially since the 13 90 at tier 9 got a nice pen buff at the expense of clip potential. I can see the French LT's becoming good hit-and-run assassins, and this thing was really fun to play. Besides, LT missions won't do themselves!
