I wasn't arguing the Ten Storms changes were an improvement to the set at all. I probably fall somewhere in between you and Wub on this one.
I was annoyed by the changes, especially because at the time of the changes, the three pieces I still needed were the gloves, shoulders, and BP, and I was drooling over the fact that getting those three would put me at +600 to healing, which I'd been aiming for just as a general benchmark for a while. Oh well, that'll have to wait.
The change to the gloves and BP really isn't that big a deal in the grand scheme of things, though. It's a couple dozen points of healing lost, and some damage gained.
The shoulders change is dumb, but I will admit to some degree of superficiality and say that I'll wear them anyway (and apply my Z'G shoulder enchant that I have sitting around waiting for them) for looks and the feeling of progression.
Once we've mastered AQ40, I plan on having 5-piece Stormcaller + 3-piece TS for 2.1s chain heal with the chain heal bonus as my full-time combo.
It's somewhat irrational of me -- I'll freely admit that part of it is just "well, this is higher ilvl and it drops later in the game so I should wear it" and that's what I'm sticking with. But really, I'll still have all the EF around if it's needed.
I've grown accustomed to raiding without the +10yd bonus and it's really not a big deal. I swap in a third piece of EF for the fights where I really need that extra radius (dropping totems for a tank in a precarious position, or dropping tremors for tanks). 5-piece EF is nice, but I don't need it. There isn't really a fight in the game on which I run out of mana these days, and I don't really chug mana pots except maybe on Nef after a shaman yell that burned ALL my mana. If, in AQ, I find mana becomes an issue again, I'll certainly swap back to 5/3 for those fights.
Now, my other point from that thread is that while the changes to the set do not personally completely suit my playstyle, I understand the aim of the set designers. Personally, I think the class sets should be more hybrid than they are. I like the idea behind the AQ40 sets from a pure design perspective. Make the class sets something that is equally useful to all sorts of talent builds and roles within a class. Stormcaller has its benefits for healers, but it's also pretty good for an enhancement or elemental shaman. Genesis is good for healing but also for feral damage. Conqueror's is something you can tank and DPS in without having to switch. And so forth.
Then make your nonset loot highly specialized. Make nonset pieces with better tank stats than Conqueror's and nonset pieces with better DPS stats. Make pure feral leather and massive +healing cloth. (Take a look at the Robes 4 down in the second column here:

My only complaint was that since Helm of the Lifegiver, Blizzard seems to have forgotten that some shamans are pure Restoration and focus on their ability to heal. Helm of the Lifegiver was a really well-designed item, except for the fact that it was ilvl 62 (!! -- that's lower than Z'G loot -- req lvl 57) which makes almost anything else quickly surpass it. But since then, we really don't have much. So yeah, what I'd like would be a hybrid class set with good regen, +caster stats, some +str/agi, and +dam/crit too. And then str/agi/crit mail, healing/regen mail, and other selections, so we can truly mix and match.
