I haven't seen any criticism that was not constructive. People are entitled to their opinions.
Naturally, most posts regarding the patch WILL be criticism, because those who are content will tend to not say anything at all.
To those who think people who have issues should just take their money elsewhere, you're being irrational. They simply haven't done anything to the game you disagree with. If they decided to replace all the planes with flying clown cars and fairies (no, the C205 and LA7, respectively, do not count), I'm sure you'd have a word or two to say about it.
Put it this way: if there were no criticism...if everyone thought everything was perfect all the time...you'd be playing Air Warrior still.
Now about those ground textures...
