Wait are people actually looking at their hotas setups when 2d flying? Isn't the whole point of a hotas to know where everything is and be easily accessible? Il2 doesn't really command a whole lot from the user. If you fly axis you literally just need to know where your throttle and stick are. This is the first time I am hearing people concerned about button engagement.
Can't say I look at my setup ever, maybe if you play once a year it's an issue. If you play at least once a week you should know where your inputs are. Using a keyboard is a different story. Was still able to type proficiently, I don't look at the keyboard when I type either. Just getting on the correct area of the keyboard can be a challenge. I guess if you're a grandpa that stabs keys with their index fingers while hovering over it then yeah it might be an issue. Think the immersion is well worth it.
The people complaining about picture quality have obviously not used anything beyond a rift/vive. That's apparent from the comments in this thread.
