Im sorry but this is just pure whine.. Wow is not about staying lvl 19 or 29 or whatever its about reaching max lvl and playing.. If you think Blizzard taking steps to improve the overall experience of the game for all us "normal" players. And think they are gonna take your ideas and listen to them your dead wrong.
And how would you twink without a high lvl C getting you the enchants you need in the first place tell me that ? im pretty sure that real hardcore twinking is about using tons of gold on AH for hard to get twink weapons and armors and if im not mistaking making thousands of gold as a lvl 19 is kinda hard without gaining XP..
So your reasoning is flawed, your entire argument is just BS cause your playing the game wrong.
and yes you are playing the game wrong.. Its like playing counter-strike and instead of shooting eachother you decide to make a dance video... YOU ARE PLAYING IT WRONG DEWD! and dont blame the designers they made the game as it is its you whos playing their product wrong.
