LOL, you are absent for 2 weeks and worry about being rusty, I've been away for about 17 months now and I am really struggling to keep up. It's like being a new player all over again. I can kick myself as I keep doing noobish things like running into grenades and flamers, and shooting at the enemy's feet when getting all panicky on a 1-1 combat, LOL.
Best Wishes,
Giggles.
