Did you just stand on one of the stones that lets you see stealth. Get it wait for them to show and smoke them. I know it sounds easier said than done but still 4 or 5 vs two should have enabled you to find them at some point and bring a match to its inevitable end. But I have dealt with rogues and I really think they are OP with the ability to outheal a healer in arena while doing obscene amounts of damage. I just wish my healer could do as much damage as a DPSer can. Then it would be even with rogues, warrior, blood DK, feral druids and retadins... but no... wont happen. I have stopped PVPing with a healer because they don't add any value in the 2s category.
