Frankly no, if this means dont have any new customizable options for our characters...
Look at the Lightforged Draenei... what a waste. They are only just a new haircuts or tattoos of the current Draenei. Story side and visually it would have been more interesting to have Eredar or Man'ari...
But with Lightforged Draenei, after 12 years Blizzard gave us only the chance to pay a race change just to get a new haircut or horns ^^;
If, all the new Allied races are things like that... we can see in the future only races that are a visual upgrade for the actual races, with no back story, just an excuse to give us an option to have new haircuts.
