Not gonna lie, I think the people who like positionals are just a loud minority. if they got rid of all of them tomorrow you'd see a huge stink about it but the actual amount of melee players would remain largely unchanged. Kinda like how that healer's strike went.
No is isn't. Name one other game with melee that has positionals. Cause I can name many with cast times for casters. The identity of melee is being up close and personal. That's it. The built in difficulty is needing to work around enemies moving and AE's around them.
Also I'm pretty sure the reason smn is such a contentious job is because it effectively is just the same 4 or 5 buttons over and over, not cause cast times are removed.
