Item level requirements for all the dungeons

[Zojha]

Maybe if the demand for crafted gear got higher the prices would decrease.

According to basic economics, higher demand equals higher prices given constant supply. What we would want instead is a higher supply of crafted items. And that would require crafting/gathering to become "fun" for the masses. Good luck. By the by, crafting and gathering would become much less profitable as a byproduct.

As for gear through FATEs - we already do that for lower content to a degree, via company seals which can be exchanged for gear. So a similar (or the same) system can be conveniently used for HW as well.

Are we going to forget that you can buy ilv130 gear from vendors prior level 52 and entering Dusk Vigil. They aren't as good as 2.0 endgame ilv130 gear but massively better over the ilv90 gear.

I don't think that's quite correct - you can get 120 blue gear via tomestones in Mor Dhona (handy if you do MSQ roulette for leveling!) and 115 white gear from vendors in Ishgard. Dusk Vigil starts at 51, so most people generally would want to level there, especially since you get chain boni. You can also upgrade the 120 blue gear to 130, but you need carbontwines for that, which either require hunting or raiding I think. Might be wrong on that one, tho.
