So if you follow the megaman leaker guy he has stated the two exotics people are looking forward too in the coming weeks... One was mida which xur sold weeks back and next is thunderlord on may 8th. My personal opinion is we will not see the gjallarhorn any time soon unless bungie puts it up. With that being said max your chances with three characters, do your nightfalls and at least get the exotic chest on normal and hard thats 6 chances right there. Crotas end do that raid as well.
