After new plane physics the BF109 became über plane. Hurricane just sucks nowdays in Gazala. BF109 outturns, outruns and climbs faster. The balance was good in 2.15 though now it is just well...
Only way to win is to try to get out of plane camped base and fly high and then surprise the BF109 and hope he doesn't understand to evade you. In my opinion this is serious issue, flying BF109 doesn't feel satisfying as its obvious that you win and flying in Hurri is just frustrating.
In Totalize the problem isn't as bad but there it would be nice to see some strengths on Allied planes as well.
In 2.15 balance was perfect Allied planes had their own strengths they could use to achieve victory and axis planes their own. Now Axis planes outclass allied in almost every aspect.
