Is there an assumption that AX combat is only engaged in by those interested in PvP?
I'm not specifically speaking about AX, as you well know, but even there, in its initial, unwatered down form, this proved to be the case.
I would genuinely say yes predominately this was the case, which is why you got folks like GluttonyFang or other players who wore their 'combat badge' on their sleeve so to speak, championing things like AXO (or whatever it was called), leading the charge on understanding the AI/meta and learning the processes required to defeat it, whilst others (from what I saw) complained bitterly from the Forum Consensus was bitter complaining about how hard/unrewarding (ah, cr/hr) it was.
Much like we saw with the watering down of ATF Response (once PvE playing BGS groups realised (or experienced) that they could be on the recieving end of it as well, or the post engineers AI overhaul you and I so often talk about.
