I'd say that it's less about CC needing a purge than CC counters needing work (We don't need more CC counter, we need better quality of CC counter).
I believe that having tools to interrupt other players is an healthy thing, however I don't think that long cast time CC with long lasting effect are an healthy thing. Stability need to stop being a "CC aegis", it need to reduce CC effects by 100% over a set duration without removing the "interrupt" part of the differents CCs.
ANet's devs really need to understand that being CC locked just isn't "fun".
