Whats that about needing 3* for event battles ? Is it a prerequisite that you have to have them as mandatory units, or is it more like "you have to have them, coz there is not enought knights yet for each nation to fill it with better girls" ?

I think all 6* are guaranteed to have a 2nd Bloomed form. Not so sure about all 5* though. Still a long way to go till that is implemented. Bipina Cosmos, though I dont have you, I wish you to get that second form as soon as possible, coz what your artist did to you with the first Evo art, is b*tch slap x1000 deserving.

And yes those extra rewards are ridiculous BS (and no I dont mean Balistic Skill >___>). Seeds ? Coins ? Are you bloody serious ? I cry tears of sadness whenever I get fckn coins from the Gathering. At this point I have soo much that After I spend half a day upgrading equipment I still have more then to know what to do with.
