Feat of Strength idea:
Expand upon the "Ahead of the Curve" styled Feat of Strength. *
* - With the new Legacy Tab (impending WoD implementation) and Blizzard seemingly awarding Feats of Strength for doing every current raid (and even individual bosses), I think it makes sense to expand this type of Feat of Strength to include previous expansions dating back to Wrath of the Lich King.
For example:
"Ahead of the Curve - Wrath of the Lich King"
- In this Feat there is a list of all available WoTLK raids and they'd either be Highlighted (yes) or Un-highlighted (no) for if they did indeed complete each raid before the subsequent raid-patch content's release.
But how?
All information is at hand dating back to the start of Wrath of the Lich King with exact dates of completion.
Where?
(Start) Achievements-->Dungeons and Raids-->Lich King Raids-->X or Y Raid Completion Achievement (Finish).
All you have to do is see when a raid was implemented-->Find out when the next tier was launched-->And now you have your exact dates to match it all up with your Raid Completion Dates.
For Example:
Mike the Rogue completed Ulduar on May 12th, 2009 (Patch 3.1). Patch 3.2 (Trial of the Crusader) didn't drop until August 4th, 2009. Therefore, Mike the Rogue would be awarded the "Ahead of the Curve: Ulduar" achievement for Ulduar.
Additionally:
Burning Crusade and more importantly Classic are outliers in this scenario and, the way I see it, a couple things could be done to manage them.
"Ahead of the Curve - The Burning Crusade" and "Ahead of the Curve - World of Warcraft"
1 - You could have a similar scenario play out and your indicator in these ones would simply be if they completed X or Y raid before the release of the subsequent expansion's release.
OR
2 - Only start these 'Ahead of the Curve' achievements with the start of Wrath of the Lich King so as not to cause problems with the on-going achievement dates not being awarded properly for TBC/Classic.**
** - There is a flaw in The Burning Crusade and Classic WoW's Raid Completion dates because they were only awarded if you had an item or completed a quest(e.g. Head of Onyxia, Eye of C'Thun) from that raid's final boss. If, and only then, you would be awarded said Achievements/Feats. There are many people who completed raids (SSC/TK/BT/SWP, lvl 60 ZG, lvl 60 Ony) that never were awarded their Raid Completion Achievements (from that specific expansion) and Feats of Strength because Blizzard's system has flawed ways to recognize if you did in fact complete said raid.
and finally..
Addressing "Cutting Edge":
This is as far as I've gotten with this idea. I suppose something could be done for most of the WoTLK raids in terms of 'Cutting Edge' as well. Either..
1 - None could be created at all
OR
2 - Specific ones for hard modes like Sartharion (10/25m 3 Drake), Yogg Saron ( 10/25m 0 Lights), Algalon the Observer (10/25m a la Ra-den), and Lich King (10/25m Heroic) could be created as well to honor those achievements.
