I simply can't agree that positionals + Mudra is too much.
I can understand the whole peripheral argument when it comes to button bloat, but not in regards to this.
You can easily set key binds to accommodate the Mudras to use in combinations with movement.
You should have to anyway, since you should be able to cast Mudras on the move with no delay. If you can't, you're already losing dps.
This is just a systemized and more challenging version of that.
I find Monk too easy outside of positionals, and NIN too easy outside of Mudras.
I'm not a perfect player or the most skilled, but I like challenging rotations and fitting them into fighting scenarios.
I've even tested working with Mudras while pretending there's fixed positionals, it's really not that bad.
The more there is to work with, the higher the skill cap.
That means there's more to work towards and that's a good thing imo.
I agree the Devs shouldn't have pulled a bait and switch.
But that's because I think they should've added positionals to begin with.
Ninjas multi-task a few things. It's a bit of a theme.
They're like a bag of tricks.
They have the oGCD activity similar to DRG and Bard, as well as similar utility as a BRD and the combo system (as opposed to stance) like DRG (and well, PLD + WAR, but I'm talking about dps).
They have the attack speed of a MNK, so now they're adding positionals too.
Maybe that's where some people draw the line, but I think it's a good addition and adds challenging gameplay in a good way.
Again, you should already be mastering how to move with ninjutsu anyway, this simply adds it rotationally.
So I don't think it's a bad fit. Actually, I think it's a perfect fit for the Job that has faster movement and should be about precision striking (not just wailing at the back).
Worst case scenario if a player sticks with NIN but can't keep up with moving with Mudra, they'll do less dps delaying the Mudra.
That shouldn't hold back a great design.
It's not like they're adding button bloat and overwhelming mechanics, since it's working with things you already have (the movement buttons).
