My thoughts in bold

Bullets don't seem to hit where you're aiming more then half the time.
Iron sighting will give much better accuracy. There's also modules to increase your accuracy.There's a 2-3 second lag between sprinting and melee,
It's instant for me.hip firing and ADS firing to melee,
I assume you're referring to lag? Again, instant for me.there's lag when switching weapons,
weapon to grenade.
I will note that switching to pistol seems to take a little longer than i'd prefer but this could quite likely be a gameplay balance so that people don't instantly whip out pistols to finish people off. With regards to grenades, have you tried double tapping Y to equip them?It takes too long to get into a firefight, you use too much of the suits power sprinting to get into a fire fight which makes the other suit abilities inert.
I've found the action to be quite constant. In game modes like Crash Site i find i'll encounter one or two people whilst heading towards the point and when securing the pod it can seriously become all out chaos. Great fun.The slide is much shorter then the preview videos would have you believe.
You slide for a good 3-5m. I don't believe it was blown out of proportion in preview videos. I think the demo briefing video accurately represents the sliding distance (although it seems longer because the clip is cut and shut from different angles)The power stomp is silly and doesn't work unless you land directly on an opponents head.
Air stomp usefulness is calculated by jump height. The greater the height you land from, the more damage you do. Practice doing air stomps from up high. Nano vision is supposed to be the counter balance to stealth but only shows already visible players and players that are in stealth don't give off the blue signatures they're supposed to in nano vision.
I believe things like these are still being tweaked but good to get feedback on it.The game feels like its heavily balanced for the suit modules. Meaning, the gameplay improves as you unlock the various modules. The game should play awesome without the suit modules and even more awesome with the suit modules in play.
I don't really get that feeling. The modules i use enable me to air stomp, reload faster and detect cloakers better. Whilst air stomping is a lot of fun, i don't believe the game wouldn't be fun without those modules.
I'll say probably most of the weapon switching lag and weapon to grenade switch lag is a combination of the p2p netcode and the animation I'm getting on my screen.
If I double tap Y and pull the trigger, I'll immediate throw the grenade skipping the switch animation. If this is the case and I can start shooting opponents before the switch animation finishes then the animations need sped up. I've also noticed if I'm host the lag is less noticeable.
And in regards to your reasoning behind air stomp. If its usefulness is as limited as that then it needs to be a default move and not take up a spot in my module enhancements. If its uses are very limited it enhances nothing. There are other mods that are far more useful then that. It should at least contextually stun your opponent(depending on proximity) to counter the recovery time. In its current state the air stomp is a junk mod and the time and resources spent developing it were a waste.
If the mods aren't fun and useful then it becomes only something that Crytek has to pad a bullet point checklist. "hey look at ALL these features" "buy our product because it has ALL this stuff"
If features aren't worth while, useful, and fun then they aren't features. It makes me wonder how many other mods are in the game to pad the feature list?
