I could honestly run with any of the dragons and be fine with them; it's all just a matter of preference, yeah. I would have jumped on the Shiva Dragon train myself had it not been for the fact that it would be :effort: to get everything up and running since fire is my weakest attribute by a long shot. Got a good amount of subs for it, but none of them are leveled and skilled, y'know? Technically speaking I should really get Neptune Dragon because I don't really have any super-heavy-hitting water types yet, but plenty of water rows and utilities. Odin Dragon has not got much of my attention. Ra Dragon is absolutely broken-amazing, but... I don't really want him, I guess? I have Awoken Ra already and pretty much every "match 4" god there is, I guess, but I'm just not feeling him personally. I know he's amazing but having to match all six orbs for max damage seems like a pain in the ass.
Yomi Dragon is kind of a balance of power, stats, and utility all in one, which appeals to me since that makes it pretty versatile overall. I've always been fond of bindproof bind clearers though; especially ones that can make hearts. Yomi Dragon does all that and then some, as it makes dark, has a haste, and has a strong LS too. The fact that it's just as good as a sub as it is a leader is a big selling point for me, too, since it's kind of a jack of all trades as a bindproof stat stick utility slot. That means I'll get the most use out of it than the others, since I can basically throw it on any dark team and it'll be pretty solid, especially considering that it instantly makes TPAs and hearts to work with.
tl;dr I can make it work and more importantly, it was the sub I was wanting for Awoken Tsukuyomi-- something that can deal with binds well without having poor stats. The only thing that stops it from being an amazing leader rather than just a really good one is the inability to get 100% SBR with dark god subs alone, but there is always time for one of those to come along (and possibly exist by the time Yomi Dragon is released in NA).
