Zenimax don't you understand players don't want a grind? Considering how boring gear is anyway (with nothing more than slight stat increases) it's a wonder anyone crafts. But to add insult to injury you make materials far too rare and don't provide a reasonable way to get them from the community (ie no auction house).
Please make adjustments to these areas and other quality of life issues so that we can expect the game to stay healthy and not lose customers.
Oh and check your math. Three attempts to refine to epic at 80 percent with 3 failures means your math is broken. Probably intentionally.
