Well this is kinda the same as min/maxing.

The use of focus in your macro's allows the basic joe the quickest and easiest route for multiboxing. As we get further along in our boxing adventures we find things that help us improve our play. Whether that means we move onto an FTL setup or a more quick response type setup for things like PVP where less lag for target switching can mean worlds of difference.

I see it much along the lines of the available software as well. Starting off Keyclone is awesome. DL, buy it and start multiboxing. Then you may choose to move onto other software that might meet your needs a little more. Hotkeynet, innserspace, Octopus.

To each his own but that's just how I view it.
