A few thing off the top of my head: - getting into a battle is slow. ex: in juggernault mode I will never be it at start but on flash 80% of the time it's me. - finding a pro battle is abysmal. For instance you choose a battle then you get loaded to another page to see who's playing then you decide no that one's not for you, so you go back and every setting you choose is erased so another 3 clicks and time lost to get it back. - if I exit fullscreen then I have to go to garage to get it back while in battle -changing equipement in battle is slower and that's crucial. -pause is different when you die - can't see alterations - the general lobby is not user friendly. Just too many clicks here and there to do one thing that would take less time in flash - I lag a little / the game is less fluent or responsive. My shots are just better in flash.
