Sort of adds to the problem if lower level strikes offer more keys than higher level strikes. I guess if the rewards are based on light level and not strike level I guess it's alright. But I'm well over 100 strikes and have gotten 5 keys, 4 of which got me dual warlock bonds. But I've got maybe 4 or 5 strike rewards the old way too, at least now I can pick which strike I want to try and get something from.
