I used the crafting/potion/enchantment "exploit" I guess you would call it, really early on when the game came out, I was probably one of the first to figure it out since I read about it after I had started doing it myself. Those weapons/armor are OP enough. I don't use them much anymore, well, kind of. I have a set of Vamp armor that I made legendary, but I have been using bound weapons and spells lately. So much more enjoyable, the tougher enemies actually have a chance to kill me, and dragon fights are hectic.
Call it what it is, broken, not endgame. We all play for different reasons, well, fun is usually universal but killing a legendary dragon in a single hit is not fun to me. It is boring, and takes so much out of this fantastic game.
