New items to customize racial abilities

A thought occurs to me the other day about a new set of items that could be o0implemented into WoW, without too much difficulty which could breathe a bit more strategy to the game, that of race specific items. This idea was spawned from the thought of how similar characters of the same class, yet different races are. Take for example a gnome warrior and a tauren warrior. Both can use the same weapon and armor despite the gnome being 1/4th the size of a tauren and both can use all the abilities exclusive to warriors. The only difference is the racial abilities they can use. For this discussion let us focus on just war stomp and escape artist. Imagine an item, a ring or perhaps a trinket, that is used exclusively by a particular race. The tauren could equip said item, and perhaps the war stomps cool down is reduced by 30 seconds, or has a 12 yard range instead of 8. The gnome could equip a similar item and could perhaps be immune to all snaring effects for 3 seconds after it was used, or it can remove all slowing effects such as crippling poison or slow.
This would change the way people pvp dramatically. In an arena battle, people would no longer say "Ok, we have a warrior, a rogue and a priest" and would instead say "Ok, we have a gnome warrior, human rogue and a dwarf priest." This could easily give people to further customize their character the way they want. Inscription is going to give many people a way to fine tune the abilities of their class, my idea is to give people a way to fine tune their race! Perhaps Blizzard does not even need to make these items a trinket or any slot currently available, but they could create a new slot for each character. Perhaps make them a "tattoo" slot on our character tab which could be applied in the same way gems are socketed into some items. I for one think this is an idea with no negatives and can only improve the customization, and therefore the quality of the game.
