Love this thread!
Vanilla:
A benched guildmember organised a hell of a lot of horde players, and with the help of our rival Alliance guild they stood in line from AQ Entrance up to the Cenarion hold to cheer at us, after our C'thun server first.
Getting out ("guys, don't port away, leave by entrance"), that line of horde and alliance players cheering, server lagging, just after scoring that firstkill, big emotions, really!
BC:
Playing Retri Pally on horde, going for a trial run with a new guild, getting their 'best damagedealer' Warlock to tears by outdpsing him (and getting weird looks from the rogue for having equiped some of his BiS gear). Guildinvite before end of raid.
WotLK:
Completing hardmode mounts in Ulduar and ICC. Not only for doing them, but also for those really nice encounters and mechanics.
Cata:
Levelling in Hyal. Raids were meh, not enough raidcontent (fast enough), guild disbanded, i paused playing.
MoP:
-missed-
WoD:
Didn't get to raid, didn't do really much. Maybe getting both Azzinoth Glaives on my Warlock before finally getting that felhound staff :-p
Legion:
Loved the DH intro quest series!
Back into raiding. Loved mage tower with DH and Disc Priest.
Even though we were really late, even for casuals standard, our KJ firstkill felt really good, with that rag-tag-group.
BfA:
Sadly nothing really outstanding despite the hype for islands.
