"Grind" is relative, IMO. I see having to farm mobs or chase down artifacts to fund my EWar bots as mindnumbingly grindy. (For some, OTOH, PvE and artifacting are awesome and the only things worth doing in PO.) Apart from these, the "variety of ways" a PvPer can fund themselves amounts to an alt account trained for a more lucrative profession, or being good enough at PvP to raid for profit. Regardless, that "a combat player does not have to grind" is ridiculous.
On the "terrain familiarity" bit, I may have misread post #39 as a response to me, when I now realize it could have been meant for EXILE CORP. Assuming it was directed at me, my point was roughly aimed at the fact that repeating tasks for slight personal gains each time wears many masks, and doesn't have to manifest as slowly-changing variables in a character file to qualify as a grind.
But, fine, if "grind" is only and exactly some kind of repetitive task whose sole purpose is to run up a particular quantifiable attribute at a predictable rate, then yeah, you're grinding and I'm not. If grinding, however, is more generously defined as something repetitive you don't like doing that enables something you do like doing, we are both definitely grinding and probably in several different ways.
I'm also pretty sure I suggested to replace assignment-sourced reputation with one that comes simply from being a frequent user of a particular facility (no assignments). I sympathize with your complaint. Having to geoscan and bounty-hunt to get a factory manager to like you is absurd. OTOH, pure extension-based efficiency seems just as off to me as having to run unrelated missions.
Maybe, at heart, the complaint has more to do with it being too hard to turn a profit as a younger player? Obviously reputation wouldn't be such a long grind (even in the current system) if it was for better--as opposed to merely some--profit. As you said, an upcoming patch might help with that, but more could probably be done to fix the pacing for indies. Otherwise, I'd just have to wonder how someone can choose the grindiest profession of every MMO ever and then complain about having to grind.
