Not to be Rude or anything, but here are some things that i noticed while you played Proxy (Proxy is my main).
No Sense of Surroundings (You want to flank and run to the “door” your team closed a Minute ago and are stuck for some Time) or even your own Weapons (You are in Close Combat with Sec, draw out Cricket bat and after few missed swings, switch back to Sec with 2 shots instead of your shottie, which is full). You are also seem to lack some Basics (Get in Combat, See you are outnumbered and run away, but with Primary out, not switch to melee). Your Mine plants are also so basic, i think you get the idea for them on the fly and have no idea how exactly the mines work, sure they kill some guys, but just because the enemies are pretty unaware also.
The Aura Part(Aura is my Secondary) is just a glimpse into Aura with no insight. Heal, Revive, Shoot. Thats it. No Movement, no Jumps, no Advance strats at all. Its so basic, i think.
Like i said i dont want to offend you or so, but just because you have some lvl advantage does not mean you know to play these two Mercs at all.
Nader i did watch but will not comment, due to my lack of experience with her.
