Can we get a new currency for grinding

so grinding TT`s are suuper hard to grind like in wot its easy cus you need to grind 1 line but in warthunder you need to grind like more than 3 lines for example im grinding the italy air tree and i ground 4 lines and that wasnt enough because in rank five even though i had grinded 4 lines it still wasnt enough amount of vehicels to pass rank 5 so i am now forced to grind the line that i didnt even start grinding. but in wot after every battle you get a bit of free xp which helps grinding but in wt GE was really only used to progress little by little but then more and more GE vehicles came so ge got more expensive and now grinding is impossible

wot also has only 10 vehicles to grind for a line. now imagine that being 30 vehicle line to grind. thats war thunder. and just like in wot, you need more xp the higher in the tier you are to grind. except where wot is till tier 10, wt is till tier 30. so yea, the grind is way higher, cause you need to grind much further.

i do like the idea of free xp, which technically, warthunder has. except its not free xp, its payable xp. i dont even understand why gaijin bothers with adding it in hte results screen. as an incentive to make us pay for the grind? i dunno. you get an equal amount of payable xp as you get with normal xp.

i would also like to see that you dont need the previous vehicle to unlock the next vehicle in line. i think that is a dumb mechanic gaijin added. once you unlock the next rank, you should be allowed to freely grind the vehicles in that rank.

If Gaijin makes the grind like WOT, then everyone will be trying to rush to top tier, which causes more problems because no one will have a proper lineup.
