Okay, 6.1 is out, it's live and I've just logged in to wail on a dummy and "try it out for myself" as per Yoshi P's instructions and...
It looks like every SAM player was right. Shocker.
The rotation feels so unsatisfying to pull off now and the fact that Shinten is the only Kenki dump we have is annoying as hell and creates a situation that reminds me a lot of 4.X DRK's Dark Arts spam, or current SGE Eukrasia spam. I'm really just weaving in Shinten because the red bar wants me to and there's nothing else to spend the resource on. If the goal was to strip the feel from the class then mission accomplished, but I won't be playing SAM for the rest of 6.1 - or 6.X if this is the shape of things to come. It's not about the DPS either, I'm not using a meter and I couldn't care less whether we're at the top of the charts or the bottom, this is purely about feel and personal satisfaction while playing and both have dropped significantly for me.
I don't think I'm the only one who feels this way after playing it, and I highly doubt this'll be the only thread post-patch expressing distaste with the changes. But we were instructed to try it for ourselves and then post on the official forums. Tried it out, here's my post, give me Kaiten back.
