My team is only level 12 so I by no means do I have any real extensive knowledge of the ins and outs but I do notice that getting everyone into fight range hasn't been a concern for me. The team setup is 1 warrior and 3 pallies, so I normally just charge in with the warrior then swing around to the other side of the mob and the 3 pallies are pretty much in a decent fight spot behind the mob. One problem I've noticed though would be the freaking healing. Having to stop the pallies so they can cast is annoying as hell. X( Fighting hasn't been the blast I thought it would be so far in terms of how fast I can charge into a crap ton of mobs and burn them all down but I've been told things will pick up later.

edit: Running in with one of the pallies and then turning the mob should work the same as the warrior charge. I normally don't worry about body pulling to many mobs since I have all the heals and rocking the healing potions. Even though I've died a lot by not worrying but hey that's probably more so because I suck at healing :S .
