1. In the context of what you said I wouldn't take Blue Mage as being a new role, so for me at least your comment of "a new role" was out of nowhere. That's why I figured you were talking about something from another post, not the one you quoted.
2. I've said my main point multiple times, I'm honestly not sure how much clearer I can be. After a certain point the fault in communication isn't on my end but on yours. That you think I'm arguing it should or shouldn't be a healer says that you still aren't getting it, and I really don't know how many ways to reframe the same basic point of "It could be a healer and it wouldn't be weird" until you get that's my stance. That I'm arguing, again, against a stance that I've seen that to me reads as "it can't be anything but a Caster".
3. And I find your thought process difficult to parse so... woo? I'm not sure what you hope to gain by stating your opinion on my writing style, especially again as I don't find yours to be crystal clear. As far as breaking down into smaller arguments that's... kind of how discussions like this go? It's a branching tree. Core argument branches into smaller ones because of how they relate to the core argument, and so on and so forth down the line until you're ten points separated from the original main one. As I've said, both in post 167 and earlier in this thread (to say nothing of my posts where I'm not exceedingly explicit, these are simply examples of what I consider as point blank explicit as I can be without insulting your intelligence), my main points are pretty straight forward. I'm not going to say every single argument directly relates to them, but it's also possible you're reading things as arguments when they're simply comments. Saying "Red Mage and Dancer have multiple roles they could have been" is not an argument, it's simply a comment, but your reply to that comment reads as though you see it as an argument. I certainly have had arguments on Dancers specifically, and that's ultimately tied still to the overall discussion going on with regards to Geomancers, even if it's a couple points removed from the core argument.
