Sure, they may just be “fun” to some, but they do require effort and time (which is obviously so if some guilds don’t want to be bothered to gather up 100 dwarves in the Siege or work on timing Disarmed properly, or controlling their DPS for 9 Lives).

Sure, some are impossible to do for a progression-focused guild (shutout, unbroken), but others only require a little bit of time and effort, and should be rewarded. Probably more than the 0 through 5pts that it’s currently worth.

After all, everyone has their own definition of what’s making progress. For some people, getting Disarmed is a huge deal. You don’t get extra loot, but that’s not the only way to judge — consider that some of these achievements ARE needed for Glory of the Ulduar Raider

What I have done here is divide hardmodes into three different levels of difficulty. Hodir, Thorim, and FL+4 are the easiest three hardmodes. The next level of hardmodes would be XT, IC, and Vezax. The hardest level of hardmodes would be Mimi, Freya and Yogg. Finally, the last one should be worth a significant amount higher than all others as the final fight. If you add up the achieves, this gives +100, +125 and +150 based on the difficulty of the hardmode. I understand that you will likely have to tweak how that is handled to make your regression system work, but, I figured I would at least provide you some input on values of achieves.

Try something like this.

FL+1-4 should each count as each of these are a clear logical step toward progression.
Heartbreaker should count, this is a hardmode and is an actual progression encounter.
No other achievements in siege.

IC- All three should count, Brundir, Molegeim and Steelbreaker…all of these are steps toward progression. Although, because you already give credit for Brundir as a IC kill, you may leave that one out.
Kolo, Auriaya should not have any.

Freya+1-3 should have achieves
Hodir cache, Thorim’s true hardmode achieve only (there is one that just has to do with engaging while sif is there, that one doesn’t count…gotta get the kill one)
and of course, the real landmark, Firefighter.

General Vezax hardmode one and then Yogg -1-3 (we can ignore the FoS, as it is not even considered possible atm “Alone in the Darkness”.

Each of these are either progression steps toward a hardmode kill or the hardmode kill themselves.

Any other achievements are fun, but anyone that can get the kill can likely perform the achieve. Many won’t waste time until they complete the hardmodes and algalon to bullshit around for the extra minor achieves…unless they just happen to pick them up randomly. As ranking should be done solely based on actual progression and progression dates though, all other achieves really hold no significance.

If easy mode bosses worth more than its hard mode achievement, they are basically encouraging guilds to kill the bosses in easy modes first before they do hard modes.

Some guilds prefer to challenge and give themselves a try on hard mode because it is something not many guilds can do. And since it is not likely attainable by casual guilds, the decay wouldn’t be too much if the casual guild tend to complete it many weeks later (after some nerf)

@Wasserjunge – I can definitely make certain achievements worth nothing and just have them shown for the sake of fun. What achievements do you considered to be not worthy of ranking for progression (even if they are worth very little? ) ?
