Should make gentleman's agreement on stealthing at certain areas, just so you don't stealth around for 5 years, trying to catch each other, but rather getting saps somewhat off the bat. Preferably near a pillar (should be playing on Nagrand imo, or blades edge if you want fancy shit).
Both maps offer possible resets with step. I.e. play near pillar on Nagrand arena, step for movement speed, turn around a corner quick enough to gain LoS, so that the other rogue can't follow with a step on his own. Bridge on Blade's Edge just offers some fancy plays with step juking off the edges of the bridge, as well as the "hydra jump" from bridge to ramp.
GL to both participants.
