I think you are underestimating the 40 gold bonus of Wealth . It certainly has no place on a tanky dps who invests in Utility. But with it, supports can start Faerie Charm + 4 Wards (previously it was 3 wards). And now that junglers clear jungle faster w/new masteries, early wards are quite valuable.

Also you seem to have a typo or something on the Indomitable description:

Blue Ezreal, meet Rainbow Aatrox

This signature is randomly generated from a pre-selected pool of items. But assuming it didn't give you 4 defensive items or 4 boots, this build will more than likely work on Aatrox.

I see almost always a 21-9 split of mastery numbers. Why is this? I understand that 21 is needed to get the final mastery in a given set. I have a different setup for my Caitlyn 23/3/4. The extra 2 offense points are in Butcher otherwise I have the critical setup you show. The other points are in Hardiness, Summoner's Insight and Good Hands. Another example is my current Corki mastery page 15/0/15. While I don't get deep in either tree it gives a balance of the key things I feel are needed for a slow AD Carry like Corki. With this setup I get the life steal, mana, movement speed and gold.

Well, that happens for two reasons.
First of all, a lot of champions really do benefit from getting a full mastery tree. Damage dealers take offense, tanks go into defense, and supports go for the utility, and that's actually why the trees are called so.
After you've invested those 21 points, you will have 2 left. Most of the people will try to put them all into one of the remaining trees, to max one of the Second Row masteries.
However, noone says that it's a must. Different champions can take absolutely different setups, and, depending on what you want to achieve, you may change them as much as you want.
As an example, I've been playing Irelia with 9-9-12 masteries a lot after the season 2 update, and it was perfectly fine. However, if you are just starting playing with a champion, I would recommend to go traditional 21-9 until you get familiar with the champ.

Wealth allows you to have doran's + 1 pot. Doran's shield + health pot has served me well on tanks.

though not the most common thing someone will do, great! very informative and all. FORCES PPL TO RETHINK THEIR MASTERY CHOICES...especailly certain ppl :D!
