This is something I have talked about before.
The imbalance of good is also subjective if you have players with fully upgrade path adds to the domination.
Take players who spend more than half their time in planes, they would have planes fully upgraded.
Now the BF sandbox now gives that player a bigger advantage. This is where I agree with you as a few of them tell everyone that they should do the same time(while they still improve) to catch up.
I don't think skill balancing matching is good way either. A pilot v infantry only can have different skill set but if the pilot can't get a plane would they have lesser impact. Squad/team supported player general have skills points too does that make them better, of course not.
Yes, BF has became more competitive and look how that turned out.
BF needs better upgrade path, less gunho competitive setting and player count balance would make it better.
