Both of my main multiboxing teams are melee. I have been using them for about a year. I still cannot figure out what triggers the IWT issue where you chars just run right through the target. Sometimes it happens on all characters, sometimes just one retarded character will run through, sometimes it will last the entire fight until the mob is dead or I "reset" by having all my chars follow me, then hitting IWT.

It always seems to happen at the worst possible times, of course. I've tried many different things to get it to stop, but it's still very random.

I will also have times where I'll get an error that says "target too far away", which then I'll have to hit my follow key until they get close, then magically the IWT will work.
