I'm sorry but if you are a Multi-boxer, all those people saying it's a hard thing to do are obviously liars. Let me take one last shot at explaining the first point:
Right now, you can not buy anything for your Lordaeron toon. So donations made by multiboxer's right now won't have anything to do with their affiliation with Lord. it will be for there toon's on one of the realms you can buy something/max level. So yes, the Multiboxers are supporting Warmane financially, but that is because of the ability to gear/level their toons with money that the other realms offer. if you still fail to see the logic then our discussion is done.
Now for the rest:
2. Trust me, by looking at the planned prices for one piece of gear, I can tell it would take an entire 6+ months of a good salary to buy one BiS toon. No one with a life and bills and value of money will pay that much.
3.See the thing is, if an opposing SINGLE player attacked me, I will fight happily, if I lost and we was equal level then I would think 'gg he is better than me'. If I ended up against 2+ people that are individual players I would be able to flee. Why? Because they won't all attack at once, naturally they would delay their attacks (not noticing me until I get pointed out) giving me enough time to run back to my guards of the nearest quest hub. if it was a multi-boxer, the minute i'm seen I will have multiples of the same spell coming towards me, I can tank 1-3 of those but more? I'm dead before I even realize what happened, because as it's one person, there is no delay and no need to communicate.
4. You can have fun playing the game the way it was made. Not by ruining everyone else's experience.
I am a PvP'er and that was the dumbest example ever, why? Because Arena's is fair, balanced (well 3v3 anyway) and comes down to skill, teamwork and er...oh yea was actually a thing Blizz added to the game.
