While I think mutli-cheating just to experience all of the continents is the entirely wrong way to go about experiencing what the game as to offer, I can say that it would be nice if some sort of system was devised to allow newer characters to get a feel for what continent would suit their play style best.
My first three characters went to different continents and when they moved on, my fourth character went to two new continents. My fourth character also hopped realms until I found one I more or less enjoyed. Having that option for a newer person who might otherwise leave the game because the realm they picked isnt ideal would be nice.
As for multi-cheating itself, I think Indirik summed up some of the reasons why it's a nasty thing nicely. Multi-cheaters also tend to implode eventually, it seems, and drag an awful lot of people who weren't aware that it was going on down with them.
