Yeah, I gave up Summoners War for this game because I was under the impression that great units were more common in BF than SW. That's definitely true due to the tiering system in SW - 4 and especially 5* draws are - at least when I played - exceedingly rare, whereas in BF there are dozens of really good units and a 4* pull is as good as a 5 and 6*, minus the added task of promoting them up to 6*. But at least SW, with its dailies and all its special events, generally allowed you to summon once or twice a day, or do an 11-summon every two weeks or so. Minus Frontier Hunter, I think I've earned 4 gems in two weeks. Compound that with Gumi's refusal to give any decent rate-ups and this shit is straight up ridiculous.
And after my Kuda fiasco, I'd be reticent to summon even if there was a rate up =p
