Well, in the ol' SoR I liked it's synergy with Anubis, which allowed to use them against FG's instead of Quints, so I could make FG decks without

.
And as far as I remember it was nerfed only because of 2 things - the Dive+SoR combo, and something Zanz said about how it doesn't give your opponent time to counter your strategy, or something along these lines.
Well, I guess limiting SoR to 1 use of ability / turn would solve the Dive+SoR problem, but I guess when it comes to Anubis my intentions are different than what Zanz stated, so I guess it might be hard to convince Zanz.
Still, for me it's a simple Quint or SoR decision and I'd prefer SoR. It does not change the counterability of the combo (except the possibility of quanta denial draining

), but it would make Anubis more useful (I don't like the fact he's so reliant on Quint and that's the reason why most people chose Quint over Anubis).
