1. Sprinting. Sprinting is not particularly fast and to make matter worse it drains your suit. What happens in the end is that your suit drains easily if you want to move from one location to the next relatively faster and by the time you reach your destination you are good as dead because all of your suit enhancements are mute because of sprinting. Now if the sprint was as fast of the Crysis, I don't think I would mind but to for the suit energy to be drained from normally running is rather useless and over penalizing. It is made worse for Crash Site where running to the site consumes all of your energy; unless you want to casually walk to crash site.
2. Melee. Melee is to weak. I should not need to hit a person three times inorder to kill them. The move is already risky and weak makes melee attacks generally impractical. The only time it is beneficial is when the enemy is "softened" from several bullet shots leaving a very very small window of opportunity or suicide.
3. Replays are inaccurate or folks are cheating. I have seen several replays where I am shot through walls, killed without the person aiming at me. Killed in one shot (not headshot) with full health. Killed by a two shots but the replay shows significantly more. I am not sure which one it maybe.
4. Cloaking. I have experience folks shooting and killing me while cloaked and immediately returning to cloak. I don't see how this is possible. Is this an upgrade or am I missing something.
5. Respawning. There a moments where I respawn in the most illogical places or in a location where can can be gun down in less than a second. The respawn feature should be a bit smarter, avoiding situations such as these.
Thats about it I guess. I am not sure if anyone has experience these issues or these issues are normal or fine with most players.
