I've done that before @_@;;
I used to play WoW, but part way through WoTLK everything just imploded for me so I stopped.
I don't mind having to change my gear every couple of months. I do mind that when RNGod finally shines his sparkling godlike eyes of blue and magnificent cheek bones upon me, I get a new chestpiece (for example) - or I just finally get the tomestones - and.... uhm... >_> <_< >_> what now? I don't do super hard-core raiding, I don't have the time/energy/will to do that. I don't really do primals all that much either, for the same reason. I do a bunch of random things all together all the time, depending on my mood. I don't mind that I'm not BiS. If someone tries to belittle me for not having BiS materia, I'll probably just reply, "When my less than perfect materia causes us to wipe, lemme know" and proceed to rock what content I do.
I love my character. I love the mental story and images I have of her, I want materia in her gear for just a pure sense of self satisfaction that my character has glow jewels in her gear (I'd love it if melding the materia in the new gear actually altered the appearance a little, but I doubt that'll happen.) There are probably a lot of people like me who just like gathering dood-dads and progressing in any way they can as they lolly-gag around in a world and story they enjoy (and who maybe stare awkwardly at Ser Aymeric a little TOO much.)
And basically your last few sentences are the point I was trying to make earlier in a more simplistic way.
Express concerns (as you have been doing)? Cool, we can discuss that.
DOOMSAY AND DENOUNCE before seeing what is going to happen (as others tend to do and have)? I do not like you. I do not like your face. Come here so I can stab your eye with a card.
But really, a lot of the systems SE is putting in place is meant to be taken at "work at it as you do" and not "SHOVEL IT INTO YOUR MOUTH UNTIL ALL YOU CAN TASTE IS SALT" pace that so many others are adamant about doing. I hope (and I think) that you will enjoy the materia system a lot more if you do it the way you plan (or "the journey" method, as I like to call it), instead of trying to just put your nose to a grindwheel and hold it until it's a bloody mess of cartilage and tears.
