Achievements From Previous Seasons

Just had a thought of something that would be cool to have...

Ever tried to get into a pug on a fresh alt, or your first character of the season, but don't have the achievement to link the group for an invite???

I think it would be a great idea if Warmane was able to implement a custom achievement tab that was sync'd with all of your achievements from the previous season.

They would likely have to do a few things to implement this:

1. Make your achievements realm-wide so all of your characters would share achievements for each specific season.
2. Create custom achievements that don't give any achievement points, also no rewards (mounts, pets, etc.)
3. Put the label "Season X - " on the achievements so you would have something like: "Season 1 - Glory of the Naxxramas Raider" earned by the current character(whatever toon you are on at the time) character on X date
4. Import all of the achievements when you create a new character so you'll have them to link (Maybe they could make this to where you get the achievement but it doesn't give you the notification in game, that way the starting zones aren't flooded with hundreds or thousands of achievement notifications)

This would give people who have been playing every season, but aren't part of a raiding guild, the chance to link their experience or even show off realm firsts or other prestigious achievements that they worked hard for in the past but are no longer relevant in the new season.

Thoughts?
