At least in 25-man, I could be the mana tide bot in T11 when resto was in a similar state. In T12, we were okay but nothing to write home about until we reached the Ragnaros fiasco. And T13 in its entirety was an apology to restoration shaman far and wide. Raids are boring when they're designed to not screw up resto healing as we've all seen.
Today, in 10-man, all I can do for the most part is spam single-target heals and use my CDs at the right time. But that's it. I wish that something that I'm doing was totally wrong and that people could just call me a noob for not seeing what I'm doing wrong, but I'm looking at logs, I'm looking at videos, I'm looking at what other shamans do, what really GOOD shamans do, and it's no different from what I'm doing. I just do all I can do and it feels like I'm not getting 'rewarded' enough for it, if you catch what I mean. So much effort is going into what we do and we get sad results. And then another healer comes along and tells you what an easy time they're having, how they don't have any difficulties and what difficulties could you as a shaman possibly have?
In 25-man, shaman scrapes by as a support healer with mana tide and strong raid CDs, sprinkling in some light healing and keeping up rain. I've done this long enough, even in a server first guild during Cata. It's not brilliant, but it's good enough unless you get to something like Ragnaros.
In MoP's 10-man, you'd better have a good anti-depressant within reach... because 'hammering nails with a screwdriver'.
