I'm getting a little tired of seeing people using 'beta' as an excuse to stifle any and all criticism and constructive feedback. This is the precisely the best time to offer feedback as the next expansion is still being developed. Waiting until the expansion launches will simple cause even more issues as it'll be a little too late to make any major changes very easily by that point in time.
I echo what a lot of other people within this thread have pointed out in that the difference in facial features is incredibly minor. For all the flaws the older models have they at least look a lot more distinct than what has been revealed to be the case in the beta.
