Game is fun, realistic interesting etc to play but the cons outweight the pros.
If you want to play those high tech tanks and planes then just imagine it cuz it will take around few years to reach that level.
Each battle even if you play well doesnt give you satisfactory reward, I really want those DEVs to play from scratch and want them to reach the top without getting mental problems.
Although I support them for giving good content and all that even if people complain them being just copy paste items from other tree but that's false cuz vehicles are country specific and if you want to play the same vehicle from the country you want to grind then they do provide while making it as historical as possible.
My conclusion is that game is very good in terms of graphics, realism and gameplay but the reward system just hurts the players a lot like I don't understand the logic like make the player reach top tier at pace which other games provide so that later players can play whatever tier or whatever play style they want.
