After the recent changes to the Leclerc, the tank which was already the worst for BR 12.7 has been made pretty much useless. Just look at the recent player stats. The sad reality is the only chance we have of Gaijin fixing it is by added the EMBT-2018 to the German tree.
The EMBT 2018 is a Leopard 2A7 hull with a Leclerc S2 turret. However a possible problem is that Gaijin could just end up giving in a lower BR than 12.7 as the EMBT 2018 would be a LOT worse than the current Leopard 2A7. In which case France would end up still with the broken Leclerc turret with a lot worse hull at a higher BR.
