Flag Runner GvG Help

Hey guys, here's my problem:

My guild has just started GvG, and we've just hit 10wins 0losses, we've got a competent flag runner - but he is going away for a few days, and ive been designated the new runner as ive got the skillbar unlocked etc - problem is i dont have a clue what i'm doing :S.

Could someone explain to me how I'm supposed to function at the start, and throughout GvG battles - where i should be and what i should be doing.

Thanks for any info helping me to not make a fool of myself in our next GvG

well set up as r/mo, have some sprint skills, purge conditions, holy veil, smite hex etc. then sneak around depending on wat hall, and run back. your team will meet up with u half way most likely because your moving at a faster speed. Put 9 into ur wep attr. so u can be of some dmg use.
