I think, it's worthwile downloading it - so far I consider this the best patch.
Please, watch out for strange item names in the BF - I recall gamers having a problem with this. BTW, I could enter and leave the BF in act 3 with the BF catacomb key. And my experiments were then done in Act 4 with exactly this save. (I always save extra, before entering there, just out of caution).
