I love free apps with some in app purchases but...

Yeah I agree it's largely based on luck. I'll say that I did get pretty lucky with the chests I opened on here. I've spent $250 so far and opened up a total of 60 chests, 40 of the best ones at once and 20 of the Dark Prince's chests. I got two Iron Maelstroms, Tempered Battlegear (4*), Flamehunter's Garb+ (4*), Clayplate Mantle (4*), and Kaleidoscopic Starmetal Raiment (4*) along with a Storm Sorcerer (3*). All of which are decent armors with over 1,000 on each stat or better, aside from Starmetal. Anyway I agree though on drop rates from chests. It's a money sink for sure but they should definitely increase the drop rate. I will add that people on iOS seem to have better chances getting good stuff from the chests. Also buying chests in bulk seems to make the chances of getting an epic or legendary by quite a bit.

It really depends. If your into large p2w games, then in-app are a plus

[Jagerr94]

Knights and Dragons is simply a new skin on a super old business - advertising. I haven't seen the revenue breakdown but I'd bet money that is where Gree is making all of theirs.
