I finally understand why 25 man raiding guilds have been dying out.
2 months ago we merged with another guild on my realm that was 4hc and we were 3hc at the time. The merge worked out well in terms of the community and players and new guild management getting along but it really seemed to hamper progress.
Fights like ji-kun which we face rolled in 10man took a bit of time getting right in 25 man, even horridon felt easier to us on 10man. 2 weeks ago we managed to get 7hc out the way but we were battling on council a bit, also farm bosses would give us trouble during the week.
So 2 weeks ago we decided to give 10man raiding a go and split into 2 teams, 1 team managed 10hc the 1st week and my team 9hc. I have to say this tier with gear 10man raiding is far easier then 25s. So as a guild we have decided to stay 2 10man teams going forward and have the benefit of enough people for the new flexi raid system.
With the way the current rewards work now, it's no suprise 25s have been on the decline since cataclysm. All I know is that I respect 25 man progress a lot more then 10man even though I prefer 10man raiding.
