Well the Italian tree will be sparse atm, hopefully in their March patch they finish filling it out, but atm it seems there will be 20 total vehicles, allowing quick progress.
Jets are ridiculous, ridiculous grind. I have some US ones. The issue is that to even get there is crazy, and once you get there you're stuck on a slow ass low-end jet that isn't upgraded going against full decked out better jets and you need kills to get more XP... its super easy.
Yeah, I learned long ago that matchmaking in that game gets worse the higher you climb in the tiers. The most fun I had in that game was in the first two tiers or so. The higher you climb in the tiers the more and more you run into people that do nothing but grind on WT all day every day. They are just absolutely no fun to play with. Gaijin can fuck right off with that high tier garbage.
