Mounts.... We had 250 mounts and v6.2 gave us 300 mounts achievements.. Both are very hard to come by, especially, if you don' do both PvE and PvP. Personally, I collect munts whenever I can, and I'm only at 235ish..
Pets... The last achiement is "75 pets at level 25".... 75??? Serious pet collectors have 650+ and some are close to 750... Personally, I'm at 707 (plus 14 that cannot be levelled)..
Does anyone know, why there is such a big diffrence?
