Just play like always - you will be fine.
1) Never go toe to toe with an electro.
2) Let them forget about you - and kill.
3) Rely on your snap shooting skills - then you can kill - if you can't - GET BETTER.
4) Never come out of the same spot too many times - play all edges of the bunker (except the top - and even that can be played now and again).
5) Don't think your AT makes you an electro - it doesn't. Shoot lanes with it off the break - and shoot people in the open with it - other than that - forget it.
You will get it.
