TL;DR on the bottom
I've been thinking lately, with the new point and click gathering system (Which I both like and unlike) would it mess up gathering catalysts for materia? Before, to get what you wanted you had to go to a certain area and go through the minigame with FotG equipped. You weren't garenteed to get what you want, but it was effective if you had some up to date gear for that nodes level or better. Just before the last save I really started to get into materia melding. I started to make tons of gil just selling the level 20 catalysts for mining in Thanalan. So.. seems like in 2.0 then you'll have to be really lucky or have great gear to get catalysts to show when you gather in the right area? I don't recall hearing much information about HQ materials yet but am guessing it will follow a similar system. I can only imagine it would be that much harder to meld your gear; and needless to say more expensive if you purchase everything.

Please tell me that I am not the only one worrying. Thoughts welcome.

Tl;DR
How will catalyst collecting work in 2.0? Melding harder? Maybe.
