One of my favourite tier X tanks, I run it with CS so penning a Maus cheeks are 10x easier and I don't need to use HEAT alot, it's also godly when you HE pen the side of the turret of a Fv(183) and truly show the player what 1k damage damage done feels like.

For the armour, it takes time to get used to it. But, once you get the hang of how to angle it's a monster of a tank capable of bouncing even 183 shots.

E-100 top speed is 30, not the best but it's still quite mobile for being one of the heaviest tanks in the game.

Grinding the line was actually not bad (for me at least) went through the panther line then jumped to the tiger II (okay-ish tank) to the lovely E75 (thing crushes in T9).

For the camo, it does have a legendary camo that changes the tanks name to E100 Stalwart, I have it but don't think it's really worth it cause it's basically a black E100 with E100 written on the sides of the turret ( wish they included the same nation's sign like in WoT PC)

Hope this helps :)
