Epic flying......

[Shodokan]

In the long term, if you one-box a heroic, you should receive 20% of the loot.
Sure you can be lucky or unlucky on any given roll.

As a boxer, we get 100% of the loot.
If you were to evenly distribute it, that would be 20% per toon.

An epic flyer costs 5000g (plus the mount) for one toon.
If one toon is gathering 5k, it takes so long.
If five toons are each gathering 5k, it will take just as long for a lot of content.
For example, the instance option will be the same, if you go with a group that has no ups there.
For example, with your guild on farming runs.
PuGs will rarely have no one getting an up from ToC normal, but boxing you can be sure everything will DE.
So with Pugs, a boxer has a gold advantage over a solo player.

Dailies earn gold for boxers faster then for solo players.
If you keep the gold earnt on each individual toon, they should have the same gold as one-boxing the dailies.
But boxers will kill things a lot faster.
And there are routes which are boxing friendly, so all mobs drop the item or its a kill quest.
In these cases, boxing is a slight advantage.
Also, dailies are boring; if you can only bring yourself to do them 2 days a week, the boxer gets 2.5k while the solo player gets 20% of that.

A boxer definitely has the option to save up on 5x toons, for 1 toon to purchase with.
For example, gearing your tank toon on the team, is the fastest way to be able to do heroics successfully.
A 1x boxer will gear the tank much more slowly, and be unable to do heroics for say 15 days of farming.
The 5x boxer will gear their tank in 3 days of farming.
And even though the other 4 toons are not geared, having the tank geared will allow all 5 to run heroics on day 4.

Farming is the one aspect which might favor the 1x boxer.
This is because of the limited number of resources.
If you can clear 75% of an area in the time it takes before respawns (I was doing this for Primal Fire in BC at Skald), you have 3/4's the resources on one toon per hour.
With five toons, you have 100% of the resources per hour, but each toon is only making 20% of that.
So, gearing all the toons off of farming revenue, is slower boxing then not.
But if you're farming purely for gold, it is still more total gold in the same time, just not as good an option for saving for something like Epic Flyers.

This doesn't take into account things like if all characters are miners(titansteel) jewelcrafters (gems daily, + extra daily quest) or tailors (5 cooldowns per 2 weeks per type of cloth)

If say... all your toons have their secondary profession as tailoring. This means every 2 weeks you are able to make...assuming 5 boxing.

25x shadow cloth
25x mooncloth
25x spellweave 2x one of them

This means for two weeks you make a profit of... 100 x the price of cloth, most servers is approximately 80 gold per. That's an extra 8,000 gold per week for basically nothing as the materials would take you about 2 hours to get.

If you did this combined with mining (yes i know its a pain in the ass to level) you would get

100x cloth (approximately 80 gold per)
70x titansteel (last time i was on these were 80 gold per as well)

so for two weeks worth of time without really farming all that much for materials. you cold effectively earn 13600 gold per 2 weeks. Not including dailies... Which would be an extra 1000 per day..considering dailies take ~ 1.5 hours to complete. You're looking at a total of about 27600 gold every 2 weeks, with no other income other than these two professions and dailies.

If you say had 3 teams worth of characters that had those professions and the dailies were done every day (yes, i know we're getting into no life now... but this would be purely for gold)

that would be 82800.

So that means that in 1.5 months you reach gold cap. This isn't including many many things that could also bring in money.

So for you to make 82800 gold from farming TOC and DEing all the crystals while not killing the market... would take approximately 83 hours... or 3.4 days played time.

Technically JC could make much more money on a day to day basis than mining because...
The bag may contain epic gems + dragon's eyes.
You are normally gauranteed about 75-100 gold as is from the satchel. Plus each character gets an extra 11 gold every day for that daily. So... This turns out to add an extra 50 gold per day, over 14 days is another 700 gold.

So you make 375-500 + 50g per day or so. So that equals out to approximately 487 gold per day from that profession. Opposed to 400. So nearly 100 extra gold. Is it worth it? Doubtful... but if you say get 5 epic gems + 3 dragons eyes on your toons some days... that can bring in some significant extra money where the price for titansteel is always pretty much stagnant. But theres no telling what kind of cooldowns there will be in CATA. this is just talking about the next year.

Alchemy as transmutation master combined with JC could actually be very good as well to make money but also costly to level to the point where you can make the gems... but would it be worth it? That is 1 ruby per day... so that is about 750g per day

So if you were to abuse these professions for approximately 8 months you could easily break 3/4 of a million gold. If you invested much of the money into the AH and cornered market you could turn that 3/4 a million into 2 million easily.
