Should i keep those Reinforcement Material (Jewel/Gemstone) for my gear that are higher level or use them? im level 36 atm and what about those Brilliant Moonwater/Cinderlands key? keep em for lvl 45+ (or even after xpac when cap get 50)??
PS: How long does it take normaly to get a Legendary weapon if that on the game...? and are they like our storyline weapon that are upgreadable/transformable?

For the material, I generally save them when I'm at max level because the catalyst used requires a lot money. For the keys, I would save them for the bigger chests that come from dungeons that feel very hard. 

 

For the legendary weapons, I can't answer that as I personally don't know.

Legendary weapons will be atleast ten times more expensive than hongmoon weapons, but they will be able to upgrade the same way.

There should be a crafting tab in your inventory, and they don't seem to be that hard to craft. The ingredients for them are the materials you get from salvaging accessories and weapons. Instead of using accessories and weapons to upgrade directly, I think it may be cheaper to craft them into Jewel/Gemstone. Later on in the game, using weapons/accesories to upgrade directly can cost a couple silver each. If I remember correctly, crafting the reinforcement material is a small bronze fee, and using them to reinforce only cost a single bronze?

 

Use the Cinderland Key(s) now, or it'll be worthless to you later when you don't need a Cinderland weapon anymore. Obviously use it on a weapon chest that has a weapon you'll need to transform/upgrade. Same goes for the Moonwater Key, use it on a weapon chest you actually need. I don't think it really matters which Moonwater Weapon Chest you use it on, but consider how long the dungeon run takes, and whether or not you'll redo anyways for it's daily quest or trying to get it's other rewards like apparel.
