The main issues i found while trying to box in WAR was that the follow distance is to long and also kinda laggy, and they dont run to be right on top of you when you stop. So that if you want an offensive team of characters you will either have run a bit further ahread with your main to get them all in range, or bring the following characters forward upto your main with a seperate walk forward key. Also the long follow makes characters very hard to guide around the envionment, unless its completly barren as they are always getting stuck on corners and such.

Also i found that boxing more than one character on a PC is not practical as WAR breaks /follow when the active window changes, or to be more specific when focus returns to the window i was finding that follow was breaking as well. So if you want to multi-box then its looking like 1 PC per character.

Also there is no /cast facility in the macro system so you will not be able to do a /assist MyMainChar /cast myspell kind of macro hence you will always be hitting an extra key when your main changes target to get the other chars to switch there target to the mains target.
