Why wouldnt you want the best weapon? of its type, especially if you have a choice? I am pretty picky about weapons ( comes from my military background) and I would resent a game that gave you lousy, restricting and unexciting weapons, its supposed to be fun and over the top. The weapon I use doesnt have to be the best weapon in the game just one I like the best, and since loot is random its almost guaranteed to be a Legendary of some type and it will never be the same twice, I do think random loot in respect to its variance is good, I dont think that we get enough great loot on drops, especially from bosses, and that loot doesnt stay good til end of game.
I believe Sleepybadger is correct in that the combat and spell systems are the best in any game ever, thats why the loot system seems to be so glaringly unfulfilling- something so well done and good, makes any other fault no matter how small seem more obvious.
I dont remember much crafting in BG and BG2 or IWD at all. That was not really a game focus,....oh wait I do remember some partial items that if found could be combined or added to other existing items, that really isnt crafting to me that was more like hoping to find pieces of an incomplete set.
I do wish there were item sets in the game, other than Wersheep Armor, which is not terrible, it just seems to be the only one.
