Sakura has +30% to RB for all squad members. If Superbosses are indeed in Phase 2, I'll be using Team 1 (with 9 leveled rainbows including Sakura) for sure ; )
Also, agree with Drip on regular RB philosophy. If it's Friend's RB, it's up to them. Public, someone's going to nuke it anyways, I only nuke if they're under the 30 minute mark (and let's face it, in events like this that RARELY happens). If your RBs are up too long, share them with public and they'll be gone within 30 minutes easily. Them nuke-lovers that reject that KNOWLEDGE IS POWER!!! (aka, visit us on forums) ; )
