Have you actually DONE any hard modes yet? Or even cleared the instance on 25 AND 10? Because I will tell you, 10 man is MUCH easier then 25 this time around 99% of the time. We killed Yogg in 10 man in less then an hour of learning him. General in about as long. Only Mimiron was actually hard for a quick minute. I'm 8/13 on the Meta for 10 man right now, so I've done some hard modes.

Doing those same hard modes in 25 is different story. One person out of position on Thorium hard mode? 5 people die and it's a wipe. 10 man, the chain lightning hits for less, and there is more space to spread out. Steelbreaker last is a tank and spank in 10 man. 25 man, it's an arms race. XT 10 man takes a good OT, in 25 man the hard mode isn't so easy. More bombs, more voids, more damage.

25 man hard modes for the most part, are no joke. Even the normal encounters are up in difficulty from 10 man. It's a lot easier to get 10 people to do the same dance, then it is 25. With most of the 25 man hard modes requiring crazy DPS, that means less healers. Less healers in a fight with more damage. DPS having to be so strong, that lossing one or two, and it's over.

25 mans are harder this time around (sans FL). To complain and say otherwise, shows you haven't done all the content on both, to compare.
