Greetings all, I am looking for a little advice, nothing too in depth, so that I don't make any horrendous errors and end up wasting a lot of time.

After coming back to WoW from almost a year in WAR I decided to dip my toe into MB'ing and roll new characters (not that I have any uber-pimped mains anyway, pretty casual game style) and after reading up on MB'ing and being a little apprehensive I decided to walk before I could run and do a simple pally + priest dual box on the same PC using keyclone. I've actually found that it's not as complicated as it seems upon first sight and I am actually quite enjoying making up the macros and trouble shooting problems.

Anyway, I've decided now is the time to start jogging so I've started a third account which I will make DPS to complete the holy trinity. I'm thinking it may be best to make this a hunter as I can just set auto attack and concentrate on the other two. I've also thought about making a mage but am unsure which will less problematic.

Another factor that comes into play is that I have a second PC (both are similar spec, 4GB RAM, quad core, GTS 8800 / GTS 250 graphics, either can be upgraded as required) that sits on a desk next to my 'main' PC (second PC is actually the wives but she also has a laptop she can be relegated to - only uses it for facebook and photos anyway ) and I'm thinking that in the not too distant future I'll start another 2 accounts (running 4 on slave PC and 1 on master) so I can 5 box and do 5 man instances. Will the pally / priest / hunter combo make it unfeasible to add another 2 accounts or.....? Or maybe when I do go 5 box I'd be better off starting again from scratch with a new group? I see a lot of posts here extolling shaman groups but I've never played a shaman beyond 20, not sure if this will matter or not, it's not like MMO's are the most demanding of beasts.

Anyway, if anyone has been in a similar situation I'd love to hear of any problems and pitfalls you encountered along the way so that I can learn from your mistakes (rather than not learning from my own which is my forte!).

As to how I'm playing at the moment I'm using keys 1 to = on top of kb for pally and numpad keys for priest (as well as alpha keys for 'common slave' functions), not sure if this is a good way to go about things or not. Am thinking if I add a third (different) class to the mix I'll go shift + numbers on top of kb. Any advice good / bad re. this way of doing things also appreciated.
