Positionals should be in the game, anyone thinks otherwise is objectively wrong.
They've acknowledged that the gap between a bad mnk and a good mnk is massive and wanted to reduce the disparity. Positionals reward better play they might be easy to do, but going for more of them and hitting as many as possible is the challenge. Seiryu EX doesn't really prevent you hitting positionals, it prevents you from hitting as many like you can in other fights like o9s or o10s. True north is there for the moments when you can't hit them, an expression of skill finding the best places to use it.
Learning your own rotation and fight mechanics is pretty fucking easy. Oh no god forbid that you use positional to become better and do more DPS on a DPS job. It's called optimizing, you know the thing that literally every role should be doing anyways. And how are DPS checks a bad thing?...
Please don't use "bad design" without knowing what the design is trying to do. The design choice to make positionals harder to do in some fights is to make it more challenging for a player to do well in a fight. It adds an element of getting better at the game, something that should be encouraged in EX and above content. Let me put it another way, if a caster didn't have cast times and could move around just as freely as bard or machinist. Would it still be a caster?
Now you're contradicting yourself. You shouldn't be standing in-front of the boss anyways so that's a moot point. I do agree that the difference between flank and rear should be more distinct however.
This I agree with, questing on monk is harder than it should be compared to other jobs.
This tells me you've missed the point of those two pieces of content. They're "soloable" so making things that face you 24/7 have positionals would ruin it for a monk player for example.
1) Again, learn where you are able to use them and get as many possible is a skill that should be learned.
2) True
3) lol
