Since there are so few 25 man raiding guilds left we can pretty much discount there progress even if they do get a world first.
So pretty much the 10man race is the interesting one now with over 90% of all raiding guilds being 10 mans and Paragon being in the mix makes it the race to watch.
I have a feeling In extremis and Paragon will be the top 2 this patch with In extremis taking top spot as they are used to raiding as a 10man team, but will be interesting to see.
