Hi again.
Ok, now i have watched your second demo and that was much more informative.
You seemed to try to attack a bit too much on your own without taking much notice what your teammates were doing.
So you seem to be a bit too brave in some situations. If you go alone and attack multiple enemies that are capping, you will most likely die.
Sometimes, when you want to take out a key target such as a medic, it can be worth doing a suididal attack, but in most cases it is not a good idea.
So a tip is to try to follow some of your teammates and try to keep track on where your medics are and stick close to them. In such a group you can help defend each other.
Time is of course important on Gravel pit, but it is almost always better to take it a bit easy, locate some heath packs and/or medics and then attack. A good idea is to wait for some teammates to attack and distract the enemies and then make a surprise attack from some other direction (By doing some horizontal rocket jumps you can travel quickly and take them by surprise (but don't do it when you are low on health)).
Then a good idea is to try to look around you a bit more (higher sens might make this easier). Quite many times you got killed by some enemy you didn't see until it was too late. I try to look around very much so it looks like I'm paranoid..
One might think "why should I look around here. There is probably nothing of importance here.", but once one you start to look around yourself more you will get surprised of just how much you would have missed by not doing so.
To keep track of you surroundings is particulary hard if you see an enemy or something dangerous somewhere. It is then very easy to focus completely on that single danger and forget about all the rest. It takes a lot of pratice to continue to keep track of the surroundings in such situations.
Something which is also very important is to be able to estimate your own skill versus the threat you are facing. Knowing when to retreat is a crucial skill.
Usually it is not worth it to fight until the end, but better to realize that "Ok, I cannot do this alone and I am low on health, I retreat for backup and heal."
To die and wait for respawn and walk back into the action takes a lot of valuable time.
