He "nailed" his own thumb instead. And so did you.
There are a decent load of valid complaints, and nothing warrants the removal of the original flight mechanic. If both coexist, you are not negatively affected at all. You would still get the option to use 'dragonriding' flight all over Azeroth, and others who don't want it would have the option to use regular flight.
Like I already said: demanding for the removal of the original flight mechanic is nothing short of arrogant and egotistical, when both can perfectly coexist.
