Well I for one love having the chance to fly the La5 without having to worry about 190D9's, Ponys & tempests chasing me down.
Mid war arena suits me fine as long as there are a few people in there.
If there is less than 10 in midwar I just head over to early war & play there.
Either way is fun, different, challenging, and a whole new MA to learn.
(which is why so many people are so unhappy)
Either their flying style depended on picking people lower, & slower, or they can't adapt. HTC & AH is all about change, change happens in jumps, fits & starts. When it happens its go back & learn again, or walk away.
Whining, complaining, and throwing temper tantrums won't change it.
Let things settle down, HT will balance and life will go on. Then decide if you can live here or not.
