If Larian keeps being Larian, you can be sure magic bows will fall from trees.
Yeah, jokes aside this is something that somewhat worries me, given how dreadfully bad the itemization has always been in their past games.
What I'm wondering is: will Larian have the good taste and sensibility to make the powerful items "scarce" (and notable) enough to make them matter as memorable finds... or we'll be showered by constantly escalating loot every couple of hours?
Either way, anything would be an improvement over the DOS 2 approach "Whatever you just found will be made obsolete in the next 10 minutes or so".
