That's a good question. First of all I would say this: the bright side is next week this time you probably won't care because you'll have a bunch of good legendaries :) to answer you I think you should consider a few things: what light level are you, what's the difference in light on your items, what are the items, what are the perks, and do you think one leans more toward your normal play style? If you say those, I'll tell you what I would do... But in general, if the 2 are 5 light levels or less apart, I'd say infuse because your lower item will go all the way up. If there's a bigger difference it MIGHT not be worth it because your lower item won't go up the whole way to the higher light level, so you're losing some of the value. And depending on your current might level that might or might not be important.
