uhm ...not sure how to look at this without hurting someones feelings but ...

a) i was under the impression that you played on the #1 us realm in terms of pve progression? I count 25 horde guilds there that are 11/12 hardmode on 25 man ... . I mean there are at least 2k players on you realm who have killed LK on 25m (assuming 25 players per guild). If everyone has 1 alt then that's a very big skilled pool of players.
b) on my realm (which is medium to new populated) there are 2 weekly gdkp's 25m runs who go 9-10/12 on hc and kill sindra/purti & LK on normal, for months now

so really surprised to see this thread
