Not sure if right category.

Other[Mounts, Minions, Companions]:
Would it be possible to make mounts, minions and achievements (or certain non story related achievements) acount wide, or make it an option for people who want it?
For example, if you have all the Garo mounts, but your alt can't get them yet because he is too low in level, will you just never be able to have them for that alt even though you worked for them? And same for other event items you actually have on one character but not on another.
If there is a reason this is problematic, could you explain why, please?
