I use the same equipment, 100% agree about the track health and mobility being crucial to doing well in this tank. . I 3 marked it pretty quickly during the Wafflecooker E100 event, I did use a fair bit of HE for that.
Enjoying the tier 8. Pretty troll armour if you ask me. I block 1k quite regularly. Going to skip tier 9 completely. After playing with the TL-7 and Cobra, I'm really starting to enjoy the Poke > Dump your mag > Retreat gameplay. I usually target high value tanks and don't mind trading my tank for a full clip on their sides.
I thoroughly enjoyed the tier 8, the alpha and pen are much the same as the tier 10, so the matchmaking doesn't really affect you. The tier 9 I keep having to take a break from, you seem to miss way too many shots from each clip. Also at tier 8, 400 alpha is often enough to defend against most tanks at the end game, when you may be getting surrounded
I am 100k XP from the Foch B, the tier 9 Foch is very hit or miss! Some great games and some stinkers......at least it has 4 shots unlike the AMX 48 with 3....
to me the foch b is a coin flip the stat are kinda good something but ist's unlikely that you will get a game where you can shot the whole clip and not miss or not pen it's just an odd tank
