Okay, so. I've been reading a lot of forum posts about how the forge is really bad and whatnot. I'm sure, that the Developers are trying to fix this issue, but are probably maybe scratching their heads about how to do it. So, I wanted to propose a way to do it, that might maybe make people happy.

So, the deal with fire crystals. Hard to find, expensive to buy. A lot of low tier players are upset, because they up their stuff, and can't find the crystals to make it better. I would know. I could never up my Newbie equipment, because I never could find Cracked Fire Crystals. Also, at higher tiers, you have a lot of unusable fire crystals, low tier ones, that are absolutely useless at higher tier equipment. So, I propose, that in the forge, we can merge lower tier crystals, to make better ones!

Now, this idea is new to me, I just came up with it, I have no idea if anyone has posted this, but, I feel that there should be a merge requirement, to make a new crystal. Something like, To make a 5* Fire Crystal, you need 3, 4* Fire Crystals. Something like that, but the limit shouldn't be too high, or too low.
And! With 5* Equipment, you have to level up your 4* to level 10 beforehand, so it's another reason why this should make that a little easier, and not with the frustration of not finding the crystals you need to level up your gear.
