We both know I'm not going to comb your post history about how you feel about premades; I'm responding to what you've laid out here. The thing is, from what I'm reading you've seem to have lumped the existence of premades in with this bad design and lack of care. "Premade fiesta," "their own little premades," "sweaty tryhards" and emphasis on "steamrolling;" I'm picking-up a lot of jadedness on that issue. Other than that, you've alluded to the concentrated AoE meta being problematic, DRKs (both components of the meta premade comps), and the existence of super-casuals and "tryhards" and the expected outcome of that relationship.
You keep side-stepping the JP behavioral argument and brushing it off as some urban myth or meme, as if it has no effect on however FL gets designed, while admitting that you haven't done any research or seen for yourself about how their matches and groupfights tend to play out. So if you don't want to acknowledge that elephant in the room, you aren't ever going to be satisfied with whatever so-called answer you're wanting from SE in response to how NA players behave. I'll say this again, if you're actually serious about SE addressing the design choices in FL, get some feedback from JP first; otherwise you're not seeing how their half of the playerbase interacts with and feels about the design.
And spare me your philosophical analyses; this thread thus far hasn't exactly given SE a blueprint on how to improve FL (for who, really?), and the first post comes off as little more than a blogpost with some rhetorical questions. If you truly believe asking the PvPinterndeveloper to question their design choices in regards to how NA behaves to it, then you do you. I've been around here long enough to see where largescale PvP specifically falls on their priority list, so you'll have to excuse my cynicism. If you want to see FL-only changes before next expansion, I'd suggest creating a more succinct list of feedback describing exactly what issues you have with the current state of FL. Otherwise it comes off more as a rant thread.
