All of ranged play it exactly the same way, you play it that way because of how incredibly effective it is.
Shoot mob at back of pack, preferably caster who doesn't move much.
Run backwards while continuously shooting, this pulls all mobs into a conga line.
Keep running backwards until all the monsters are now dead.
Go to next room and repeat until quest finished.
This method gives safe, easy clean wins along with providing the ranged user +10,000 AC against melee attacks that are far way. I've seen Inq's solo R10's using this tactic to amazing success. All the IPS nerf does is make them take longer to use the same broken strategy of conga kiting.
I should make this my signature.
