Hi. I'm playing wow, and I have just learned about multiboxing a couple weeks ago and since then I've tried 2 boxing warrior tank / shamy healer, 5 boxing shamies, and 3 boxing mages. All of which I am doing in dungeons. Currently I am using an Autohotkey script to broadcast keys - I believe this is called a multiplexer? I am also using Jamba which has been very useful. :) As far as hardware goes I am using one comp that is pretty powerful - i7, Radeon 5970, ect, and a single 42 inch TV for a monitor.
Just to share my experiences since I'm new - I found the tank / shamy combo worked well enough until about level 18 or so where the shammy heal power was often too weak with his one heal spell to do more than 2 or 3 mobs at a time. I know it would go better with more levels though. I was enthusiastic about the 5 shammies, but I found it too difficult for me to do yet. I just get confused about which guy to heal. The three mage project I started lastly since it seemed like a very easy combination, and so far that is going real good. I've just gotten the trio to level 30. There isn't a whole lot the three of them can do to mess things up, and I guess the party gets the advantage of focus fire.
There are a couple problems that I have not yet been able to resolve. First of all, the Autohotkey script I use repeats keys when I press them. This is an undesired effect. I would rather button mash, however another problem I have that many other boxers must run across is that my keys do not often broadcast to all my characters. Is this a problem that is most often caused by hardware or software? It seems that the two problems would have to be solved at the same time since I am guessing the script I am using is only covering up the broadcasting problem by repeating keys.
I am also curious as to why when I go to wow wiki type sites AutoHotKey seems so highly recommended yet as i brows these forums most people seem to not use it. Any reason for that or no reason in particular? I guess having the creators of the programs as forum members must help.
