That's cause Magaera was nerfed..... Council is a clusterfuck and if you can't figure out how to dps the right things, interrupt, dispel and move accordingly, I doubt Council will be much easier. Not saying you as in you personally but people in general.
I'll dare say, that no Normal modes in their current state requires one specific class in order to be defeated. If you want it as easy as it gets, then sure, you can't raid without a Disc Priest. I guess that's why a guild on my own server runs 10 Disc Priest in a 10 man raid..... But for any decent guild that cleared Heroic T14 or even just Normal T14 with some Heroics, I don't think this Tier needs to be nerfed on Normal. All of the Normal bosses can be killed without a certain class, if the people in the raid knows how to play and aren't completely undergeared.
Is it nice to be able to BoP the tanks on Horridon? Ofc it is but you don't need it. My own guild killed Horridon without a single Paladin in the raid. People seem to find excuses or reasons for their failure, be it flawed game design, bad tuning or lack of X class, when it in most cases is a L2P issue. That may seem harsh but I say again, if you can't kill Normal Horridon, you won't have much of a chance on some of the later bosses. And in stead of crying for nerfs, people should go back to T14 Heroic and get some more gear or they should accept that ToT might be a bit of an overreach for them, until it gets nerfed.

I get your point, I actually do. However I don't agree with you. The middle class of raiding you say. Another think that might happen, is that several people who chose a middle class guild (raiding wise ofc), will look for a better guild in order to progress. Many people have the skill to play at a higher level than they're currently doing but with the many new 10 man guilds forming left and right, so many quality players prefer to raid with their friends - even if their friends aren't as skilled as they are. But that's a choice one must make and not about the game being overtuned.
And the "decent" guilds you're talking about, if they're half decent they should rather recruit better people, up their standards, put in more effort and realize that carrying a good friend who sucks at raiding, isn't going to get them anywhere. If they then disband, that just mean that the few good raiders will find another and better guild. And that's not a bad thing, is it?
