um... false.
If you get a helmet with your warlock that is 320 if you fuse it to your hunter whose helmet is 310. You dont get a 320. if you have 2 characters of the same you dont have to infuse. hense faster leveling.
you gain atleast 6 though, so if you infuse 320 with 310, it will come out to be Atleast 316
(I infused a 320 arms with my 314 arms, got them to 320) and then the same with my boots.
the infusion system is pretty nice
true. but OP is stating it doesnt matter. 4 light matters big time when going for top light! And also you aren't guaranteed 316. Making it even more relevant. Also, how did you get 314 arms? Thats another drop. Someone who is swapping gear with 2 hunters doesnt need that drop. So less drops needed to get to 320. Making it even easier. Hense saying it doesn't matter is far from the truth.
