Classic: Atunement to MC/BWL/AQ and Naxxramas. Long grind for mats to get rep.
TBC: Attunements like for karazhan, BT, the eye, SSC. Going through every dungeon and doing chain quests.
WOLK: No atunement, 25 and 10 man seperate lockout and seperate loot. Hardmode switches ulduar mode.
Cata: Hard raid first tier, 2nd tier being 6 easy bosses and one near impossible hardmode endboss, last tier end of expansion easy and poorly designed.
MOP: No atunements, rep requirement on items, commendation for alts to ease rep grind on alts. Perfectly tuned difficulties for raids.
What model would you choose, and would you tweak it somehow? If so, how?
Would you also include LFR in this raid model? If so, would it drop loot? Would you make it easier/harder?
Personally I'd like to see the WOLK raid model back. Seperate 10/25 lockouts. As I would run 25 mans with the guild and 10 man on the side with alts. 1 25 man altraid a week aswell. I'd have no LFR, but nerfing the previous tier in a new patch to let people see the content.
