Back to Rogue :) Anybody have an opinion about Snobs and Lightning Walls?

[Nystul]

I like to hold shift and shoot down the row of floor tiles next to a wall. To take it a step further, retreat around a corner 5 steps or so and shoot down that line. If you have enough damage to stun you can often knock the enemies back around the corner. The balrog can dance in circles all he wants in that other room, but to get to you he has to go around the corner into your line of fire. It also helps against vipers because they can't charge until they get around the corner. But the position won't hold if you wake up too many enemies.

With regards to coop, I'd rather having a rogue always shooting down the same wall than a rogue who is shooting at moving monsters. Diablo has a dirty little secret when it comes to that. Monster isn't always the same place on my screen as it is on yours.
