Limited buyable level 60 boost

Hi,

relevant realm: Onyxia

in case there will be server first achievements for leveling classes and races to level 70 on the realm (and potentially still achieve-able server first for level 60 races), consider disabling the buyable level 60 boost for Bloodelves and Draenei specifically until all class and race combinations for 60 and 70 (hence approx. 3-5 days after TBC content launched) are claimed by people that level without a buy-able boost.

or make those chars non-eligible for the server first achievements w.r.t. to leveling

There are no server first Level 60 or 70 achievements. This stupidity began in Wotlk.
