I don't get why he is a must have for Fist/Earth Main players? As an Earth main, I aim to use his High Float to Knockdown chase. The reason being this chase also sets ignite status. The other two chases do Earth damage, but I find the ignite is way more useful most of the time. Only time I use the other chase is when I can't get a team comp to work with it, or I already have ignite or something better worked into the combo.

As for Kirin, I'm happy to say I've very rarely needed to use the Deer. I was also lucky to get Flood Dragon (Low Float to High Float) as my first gold summon, and have used that ever since (pretty much). But I do find my self asking the same question as everyone else... that being, what is the main reason it costs so much more then the rest?
