Ok I get your drift, sorry if I caused offense. However, as a start group I'd highly recommend pally and 4 shamans for anyone starting out multiboxing. It's reasonably easy to set up, viable almost immediately in instances, and has viablility in PvP too. If it's good, why not recommend it. Things will become popular because they work well, nothing wrong with that. As proven by the "FOTM" phenomenon, people are unlikely to post videos of sucky groups that they can't controll and keep wiping with :O Plus given the investment in time it takes to get to 40+ I have no issues with anyone who wants to know what a decent viable group is for this or that purpose, however I do agree that 1st time posters often need to research what is already posted, or understand better their eventual aims at times.

As someone else mentioned earlier in the thread, there are other combos out there that will definately also work, but others that are less tried and tested. As is also often mentioned, there are is a much smaller body of players who actually have 70 teams to glean decent information from vs normal single 70 play. Skarlot is going a long way to proving that multi-class setups can be very powerful, and yourself Vyndree, along with the Motes, Ellay and various others are blazing a semi-unknown trail.

So I agree with the sentiment held above, my advice to any new 5 or 4 box starter would be as follows:

1) Consider your end game goals
2) Decide if you are happpy to roll with classes you are less familiar with
3) Decide (and test to 20 or 30) if you have the sort of brain that can handle and wants to experience the challenge (and the 20 fingeredness) of multiple class setups.
4) Do your research and plan it all out
5) Do what feels most fun to you... as mentioned before, it's a game, not an epic factory.

Blah blah etc, late here, champagne rambles ftw 8|
