It's often I run into trouble and am facing more than one player(and my ping is 500 lol) and I have no idea who to attack.
Usually, I continue shooting the person whom I've dealt more damage as he is more likely to die. But sometimes I have not dealt any damage to the players who are in front of me, and by the time I decide who to shoot, the three of them shoot me and I die.

If I try to run, due to the game not registering when I am hidden or not, I die just as I have for instance hidden behind a wall.

Also, this is different,but I hope you can help me. Most of the time I see the distortion of a cloaked person, but if he/she were to jump, I get totally disoriented and before I could see the cloak, now I can't find the person at all and I am dead. Or if he/she passes by me before I react..same thing just gone, then I get killed...

And when talking about being disoriented, if I am low on health(and the red flashing tint appears;or the screen flickers in grey) or I accidentally/intentionally shot from cloak, and I see the energy being zapped from me, I get totally disoriented. And so I start panicking and not paying attention to the enemy, hell I can't even see the enemy.
This happens more frequently when low on health.

There's also this particular MP sound when shooting an armored person, but it disorients me when it happens to me, when I am in armor mode and I get shot.
The sound is found in Sounds.pak->physics_bullets->physics_bullets_impacts_static.fsb. It's called "bullet_impact_nanosuit_armor". I plan to alter it.

Admins that ban C4 are idiots. Only scar + laser and Ltag deserve to be banned

there is no need to discuss this if your ping is 500.
Otherwise, run for your live, do the small bunny hops that dont need energy, cut the corners as good as possible, if you are getting shoot try to "mouse-strafe" but never jump.
