g)Work on crafting system
Less emphasis on specialist system unless there is a system to get more then 3 specialists
Usefull new skills instead of the whistle shenanigans
Improvements to the crafting interface like a back button when crafting components to the item you'r after

h)Work on gathering system
New ways of gathering perhaps involving multiple nodes and not the timed favor stuff.

y)More ways to obtain Materia
The only real somewhat efficient way to obtain crafting materia is still spiritbonding lvl 45-50 stuff. anything introduced in HW is way too RNG. And a way to get crafting/gathering V materia because there is no way atm to get them that i know of without relying on mutamix rng crap
