I personally really dislike the change, Trick being on a 1 min window is why alot of statics bring ninja's and not only just for clearing but also to add some variety to their gameplay by allowing them to dump their resources at 1 min mark. It was also integral to the identity as ninja.

Their idea was to limit the changes on the rotation as much as possible while making the nin buff 2 mins, but it's likely it won't play out that way unless they make mug a really awkward skill, like giving you ninki and raid buff. Ninja will be really awkward to play for a while, and I woulda prefered if they had actual balls to make trick 2 mins so we can use our ninjitsu in-between how we like. I imagine there's gonna be some odd timing forced downtime in dsw.

Lastly depending on the balance ninja will just end up being a worse version of monk in every single way. Ninjas has worse personal mit, no mantra, and probably will always have lower rdps by design compaired to monk. So I imagine most statics given the choice will always take monk over ninja if both players are good.
