HOLY MOTHER OF.... that's a MASSIVE kick in the balls right there!
On topic: I concur, the grinding has gotten WAY too much, especially with Ground Forces.
I mean, if you make 10.000RP per day, you will need over a month for a SINGLE Tier V vehicle!
That's just rediculous...
And we got 5 Nations, each with multiple Tier V vehicles. I am still grinding German Tanks and haven't even started with other nations Ground Forces trees.
EDIT: Another thing I need to add here, even though it isn't on-topic (but kinda related): The Silver Lion income is FAR FAR FAR too low at Tier IV-V tanks. I am unable to sustain playing tanks by playing tanks at the moment; I lost about 200k(!) SL in a single day, by only playingy my 10,5cm Tiger II, Panther F and Ferdinand (95% of the time playing the 10,5cm Tiger II), even though I am flying my FW 190 D13 whenever I can.
