As the title says, this post is about world events. We certainly need more of them: Opening of the gates of Ahn'Quiraj etc, it will allow for more diversity regarding the raiding experience which is currently limited to Naxx and Ulduar. It gets pretty boring after a while.

As a current problem, "LUNAR NEW YEAR" event hasnt started or is not shown in the calendar and it should have been active since 20th of january.

Regarding older raids, i would suggest they get a nerf to allow smaller groups to run them. Currently Sunwell Plateau is unplayable as Felmist cant be downed without 15 BiS ICC players and if not killed on his first pass he bugs the encounter. likewise Al'ar in The Eye starts it's aoe before reaching the platforms dealing insane damage to the party(nobody even wants to engage it).

Another problem is theat older sets from raids like Molten core dont apply their bonuses (giantstalkers for hunters doesnt increase pet resistances: https://www.wowhead.com/transmog-set=531/giantstalker-armor etc)
