I found all french tank (t8 to t10) cool but they are not strong in everything (especially in "alpha damage and penetration").
AMX TD line look cool but they haven't good armor, they haven't good alpha damage (dpm still enjoyable) and they can be penetrate by everyone with HUGE WEAKSPOT.
AMX heavy line is… "ok"
AMX 50 B don't have good armor and same as td line not big alpha damage. only things good about it is auto loader and mobility.
AMX M4 MLE. 54 have a good turret but have a TERRIBLE weakspot on it, damage are not alpha damage are not good and the hull armor is nor really great and the PENETRATION ARMOR is…. well, you know what I mean.
Light Line look insane for player who know how to play it (i'm not a light player)
Arty line are usefull (I HATE B-C 155 58) but in game they can be really fun to play (i'm not an arty player too)
I just want to say change my mind about french line 'cause they look soooo cool to play but sadly… Statistic don't lie ;(
I'm already sorry for my English….
