Hehee couldn't find the thread for a bit there...
okayz..so heres how you get your characters to run in tight circles in opposite directions...
you have to combine 2 movements...strafing and turning in opposite direction...so you press 2 keys at once.
My setup..in key binds for all chars i assign Q with strafe left for 2 chars and strafe right for 3 chars
then ......in key binds for all chars I assign W for turn right on ^ these2 and turn left on ^ these3 chars...

Holding down both Q and W at same time makes them circle in opposite directions at a fast running speed in a very tight circle...and tends to pull a good number of your group away from normal melee swings and back stabbers
its a charm for things like...stoneclaw... 1/3 circle...tab...chain lightning..fire nova totem...tagging most mobs and pvp players in the vicinity and taking them down..
then of course using the char focus assist/follow button concentrates remaining spells and melee on whatever is left standing...

hope this clears it up a wee bit
PS...
Its kinda funny to have 5 lvl 10's circling a 70 and lasting those extra 20 secs cause the leet noob ganker is dizzy laughing n off target...makes the inevitable amusing...lol
