10 mans are stupid easy? Sometimes yes, sometimes no. I personally think 10 man LK/Sind are harder than 25, at least in terms of the gear you're supposed to have doing them (i.e. not 25 man hardmode raiders stomping all over 10 man content).
As to you having to deal with more morons, and just wanting the gear, well, that's what you signed up for doing 25 man raiding, and it's also one of the main arguments for equalizing gear across 10s and 25s (and why I prefer 10s). I don't think dumbing down the game even more is the right way to go, given how relatively easy (as you pointed out) it already is.
EDIT: by the way, I do understand your frustration. I was a 40-man raider for a long time before I was a 25-man raider for a long time before I was a 10-man raider. I hate carrying bad players in 25s, and constantly dealing the burnout of myself and my friends. I highly recommend finding a group of solid/friendly/drama-free dudes and ladies, and going off and playing casually/raiding 10s/pvping/fucking around in general until cat, and then on throughout. It's a lot more fun and less frustrating.
