A pony for each alt you level

There is no doubt WOW's design team want you to level alts; and lots of them.  In fact the new expansion is all about leveling alts.  They are entirely re-doing the the old world so you can experience the game all over again; almost like WOW 2.0.  To make your alt leveling experience as pleasurable as possible they have implemented a number of very important tweaks to the current engine.

1. BoA heirloom items
   Purchasable with emblems, WG mark of honor, and Seal of champions.  Now you can buy shoulders, chests, trinkets, weapons to ease your leveling pain.  These things levels with you and some provides 10% XP points to quest/mob kills.  They are so cheap to get there is no reason why you should be leveling an alt with at least a few.
   
2. Cheaper/faster mounts
   Mounts are cheaper and easier to get.  Gone are the days epic land mount training is 600 GP.  These days you can grab an epic land mount at level 40 (instead 60) for a mere cost of 20 gp. Other levels of mount training is also considerable cheaper (with exception of epic flying) and the none-epic flying mount also goes faster.
3. Some trainings are now BoA
   The 1000 gp you are spending on cold weather flying is now bind to account via a book.  Too bad I had already paid normal price for my first three 80s.
4. Shoulder/head enchants that require rep grinds will be BoA in 3.3
   This just came hot off the press.  They are trying to give us should/head enchants that require northrend rep grind BoA.  This mean if you have a single toon exalted with son of hordir you can buy shoulder enchants for all of your toons.  Woot. 
5. Many special pets are now BoA
   If you have the latest give away pets from Blizzard it is more likely than not it is BoA (i.e. Mr. Chilly, Blizzard polar bear).  This mean every single character past and future will have access to that pet.  The aspect I especially like is I get these pets even if I create a new toon from scratch 1 year from today.

The above are just few examples Blizzard are hard at work to make leveling alts less of an chore.  Still, with these said there are still a lot of annoyances associate it.  Here is a list of my prime annoyance with the current system. Maybe Blizzard should consider offering the following carrots above and beyond what they are doing. 

1. Achievements across account! 
   This is a big one for me.  I have so many toons my achievements is spread all over them.   I will raid with whichever of my toon my guild needs at that moment.  I don't understand why I can't be champion of frozen waste just because I finished the last 2 wings of Naxx on my hunter instead of my priest.  Also for a harder to get achievement such as explorer doing it once is really enough. Blizzard should give option to measure achievement via account rather than a toon. For the people who enjoy grinding achivement on every toon (are there any?) there should be an option to turn it off.
   
2. Flight points
   Isn't it annoying when you start a new toon all your previous flight points are gone forever?  One of the major headache is to have to run your new alt to all the flight points you have previously explored.  Is there really a point to do this over and over again? The capability of having your toons have all the FP is already there, when you start a DK you get all the FP in Azeroth; I don't see why similar strategy can't be implemented for all our alts.
3. Mounts
   I am sure it is a nice gold sink to ask each of your toon to buy a 10K Grand Ice Mammoth.  However more likely than not most people will chose not to buy them for each of their alts.  Since you spent that sort of extraordinary money to obtain it, they really should be BoA.
4. Rare/special Pets
   I started my horde priest 2 years ago. I have collected a lot of interesting feast of strength along the way.  One of my favor pet is the original 2007 Clockwork Rocket Bot. It annoys me to no end I can't take him out unless I am playing on my priest. Just because I started my hunter 2 months later doesn't mean she shouldn't be able to enjoy it.  In my opinion all these special hard to get limited edition pets should be bind to account.

I mean really, since Blizzard want us to bring the person not the toon.  They really should put in as many incentive as possible to entice us to have many alts.  I don't see what harm could come to the game if they give a pony to each of my alts.
