How dare you assuming how i treat 2 completely different raiding experiences?
Did i came out to tell you "you want to have it easy and you raid 10 but you dont have the balls to admit it and you say i prefer it?"
Nop i don't think so
10>25 was placed not to say "it is bigger" but "it is better". It is quite clear that 10 cannot be bigger than 25, but in our case is irrelevant. Unless if you wanna stick a "pennis" in the conversation!
I liked both sizes, pre cata with preference to 25. Now i can't do both especially when heroics come into play. And guess what? Our team is not in that magic 10% of the best teams out there, and that pretty much makes it obligatory to run 10.
Go to wowprogress, and check the 10vs25 ratio in the various levels of progress in DS. At top 20 you may even conclude that 80% of the people is running 25!
