DPS plateau are normally a lot lower because of this. There are also 1000 other reasons, but that's really the main.
In 25s you'll see on a lot of HM fights them cutting even more healers, a lot more than 1/3 of them, to be able to complete a fight. With that means the healers that are kept can't just be anything. On world 1st fights priest/pally CDs have been the difference between clearing a fight and not. In 10s, you just don't have that problem. After you have the CDs you need they choose who brings the best next things. Who fills in the gaps the others miss. In the past druids hps > shamans. Now, shamans hps is fine + they have a CD. This is where you see balance come in. Even when cutting down healers isn't an option, it's because too much raid dmg is going out. And the same balance issues end up happening.
I have hardcore raided 40s and 25s since release, and 10s also now for many years. It's not about difficulty, it's about a lot of other things.
