Sometimes I find myself thinking about all the pets that could be that arent. I couldnt find a general thread for any suggestions or ideas so I thought I would start one! Who knows, maybe any really good ones might come true one day!
well, I recently did a quest line on the horde side in hillsbrad, involving Orkus and Kasha the frostwyrm. *SPOILER ALERT IF YOU HAVNT DONE THIS QUEST YET*
It is Orkus' dying wish that you look after Kasha for him and find her somewhere cold to live. I thought it would be kinda cool if a follow-up quest could exist (where maybe she was shrunken to fit in your bag or something) where you could take her to a cold place (maybe near the greech's cave, that's in a close are and looks quite chilly) to release her but instead she wants to stay with you... would be pretty sweet and remind you of a fallen friend (Orkus). There may need to be something similar for the alliance to obtain one of these (perhaps a vendor or lootable as was the case for withers from the Alliance quest Rememberance of Auberdine"). Note it would be a tiny frostwyrm not a frostwhelp like Frosty!
This was suggested by an MVP on the US forums (I did a google search - http://us.battle.net/wow/en/forum/topic/1192579336) so I'm not the only one who had this idea and I do really hope some day it becomes a reality.
There have been other ideas, but I want to hear other collector's ideas and just think about all the endless possibilities that exist!
