I don't have much to say that hasn't been said, but please know Tides of Chaos is *the* subclass feature, not the Wild Magic Surge
I tolerate the Wild Magic Surge *for* Tides of Chaos...not allowing the Tides of Chaos to reset with a Wild Magic Surge breaks the class...you literally get nothing from it
+1 – Tides should definitely reset on a surge, and also our chance of triggering a surge should be significantly increased when Tides is expended
