Some see it as interesting ...
Some see it as boring ...
Personaly i see myself somewhere in the middle ...
I dont mind neither, but honestly will rather have conditioned item that gives me something great, than flat stat boost that is practicaly invisible. :-/
How is "vulnerable to + resistant to" more visible than, let's say a ring of protection that gives you +1 AC and +1 to your ST ?
How is "+1D6 vs 2 creatures" more visible than a +1 arrow ? (%to hit increased)
I'm not against a few items like this. But I hate than most "interresting" items in the game drives the gameplay.
That's not how it's supposed to be in DnD if I trust the DMG and that's not how it works in most (C)rpg.
