I've spent all day toying with builds and genuinely trying hard not to be biased towards SR and give a fair evaluation. I can, however, conclusively state that SR is NOT responsible for the effectiveness of the Restoration-secondary builds.
Introducing Carway: (Me/Rt healers)
Norgu:
[Weapon of Remedy][Vengeful Weapon][Mend Body and Soul][Spirit Light][Protective Was Kaolai][Power Drain][Leech Signet][Death Pact Signet]
Gwen:
[Weapon of Remedy][Vengeful Weapon][Mend Body and Soul][Spirit Light][Life][Power Drain][Leech Signet][Death Pact Signet]
Restoration: 12
Inspiration: 14
Fast Cast: 4
Add any two damage dealers, and any hench you want. Healers not needed. I added a pure Necro SS and MM, but Splinter-Barragers would work, or any damage sources. Henchmen can be anything you want, but you DON'T need ANY additional healing. That's right Me/Rt! Finally those Mesmer heroes can get some exercise!
I then took these Me/Rt healers, went into Hard Mode and vanquished Pongmei Valley in 34 minutes with shitty henchmen...with NO deaths. Not convinced that was a sufficient demonstration, I took these guys to the Realm of Torment, again in Hard Mode, and proceeded to crush the crap out of mobs in Nightfallen Jahai. A friend then PMed me for help in Eternal Grove, so I went to help. I dropped the Mesmer with PWK and kept the Lifer. We did the normal 4-4 split and I easily held my side with ONLY little Gwen as a healer.
Neither Me/Rt was properly runed-out. Gwen had 13 Inspiration. They also had Illusion wands/focii. A correct rune set and a Restoration staff would further boost performance.
Next, I returned to Pongmei Valley (HM) and dropped the Me/Rts, instead using E/Rts with NO e-management at all. No monk healers, or ANY other healing. Furthermore, I intentionally played bad. I ran from mob to mob as fast as possible, didn't even pick up loot. Did not to rest unless absolutely necessary. We vanquished the zone easily.
NEVER, not once, with either build did we die because the healers ran out of energy. We did die a few times, but the healers ALWAYS had lots of energy when that happened. So, what's this say:
1) The MM
isn't crucial to the Sabway in terms of e-management. (Sab was right)
2)
Neither is SR. (Carinae was right)
3) The Restoration-secondary healing build is really, really strong.
Running it on an Ele primary with NO E-MANAGEMENT AT ALL or additional healing and we VQ'd a zone. There was some struggle with the Eles. Then I went back out and VQ'd it again with BloodRit enabled, not exactly strong e-management. Yawn, easy VQ. I didn't even try to add Ether Renewal, obviously it'll work great.
The Me/Rts performed so strongly I am going to use them on a regular basis from now on. They walked through HM ROT like butter, with the exception of the bosses. We needed Prot for the bosses. The Mesmers didn't run out of energy, but they couldn't keep up with the damage.
I took one hit for 254 damage with Dark Bond up! (No, it wasn't stripped)
That should dispell any doubt that SR is NOT responsible for the strength of the N/Rts, although it does synergize well. The Restoration skills can be easily powered from ANY e-management source. In fact, the 4x interrupts on the Me/Rts give you something SR doesn't...actual offensive capability on top of everything else. (Because two Mesmers supporting the whole team in HM ROT isn't enough
)
Previously, it was stated that there was exactly one SR supported uber-build.
Now there are Zero. People can point to ZERO SR DEPENDENT uber-builds, despite it being "godmode". Give me a break. If it was so abuseable, it would be everywhere. It would drive every other class out of business. Despite it looking so good on paper, it doesn't actually translate to that in real gameplay.
The only real solution (if one is wanted) would be to implement a cap on the number of secondary skills that can be used. Just like PvE skills,
only allow 3 secondary skills on a bar at the same time. This has the added advantage that it stops ALL secondary abuse across the board. It also enforces the concept that secondary skills are meant to augment a build, rather than BE the build. Having 6-8 skills from your secondary necessarily introduces problems, especially when dealing with hyper-efficient healing spells.
You could also simply make Restoration the primary attribute for Rits. That also breaks secondary abuse here, but it doesn't address other e-management forms. It might introduce Spawning abuse. (I don't know off the top of my head)
I think the 3-skill limit might be the best option. The situation is really a symptom of power-creep. It's clear to me though that nerfing SR would do nothing but push he whole build to another e-management form and the situation would repeat. ...or we could leave it alone.
