is us worth grinding and does it have good top tiers (I have us on rank five)
you mean ground or air?
both
Air is fine, I personally can’t say much because I don’t play Air,
But Ground is something to discuss, top tier has bad players due to the “Invencible american machinery” fallacy, they don’t know how to properly play with the vehicle, think it’s OP because they seen a bunch of military personnel fighting some guys in the middle east with 50s equipment, waste money on the M1A1 ‘Click Bait’,
Then goes into a match, dies to some other Meta like a Strv 122 or a T-80BVM and completely destroys other’s experience. Overall depending what’s your goal, it does worth. If you want certain fun 6.7 is fine with the Pershing, super armored and good weapon, 8.3 starts to be tuff but least playable.
air is one of the best in game ground is just good but not as great as germany/or sweeden
In my experience you miss out on a lot if you don’t develop most of the tech trees. I’m mostly a tank guy so mostly speaking to that side. Great vehicles to play on the US tree are the M24, M18, M41, M92, M56, the T 34 heavy can be fun. I have higher stuff to but don’t play those BRs much. Enjoy!
I tried the M4A1 76 W and that is also very fun
Currently US is the best in Air, but how long it will stay that way is determined by if/when Gaijin will implement more accurate flight models for the ARHs in the game (and what new jets are added in the future). If there are no changes to the missiles then the US might stay on top for a while, but if they fix the performance of ARHs to how they’re supposed to be (based on publicly available documents), then the US will struggle big time.
As for Ground, it’s not really worth it as the US has an average (at best) MBT, only one light tank (that is 1.3 BR higher than it’s supposed to be), the second-worse SPAA at top tier, and good CAS in terms of amount of ordnance but average in terms of ordnance range. Plus there’s a whole bunch of people who just bought their way to top tier, so it ruins things.
Here’s the GRB win rates as of yesterday, for reference (the US has been the literal worst for probably a year at this point):
US air is incredibly good, and it is the best air tree in game.
US ground is also quite good, but it is slightly lacking at high/top tier.
