It's strange, but I think my biggest complaint about how the raid system works is how short the timeout is once the 3 "helpers" confirm they are ready. I'll be waiting for a few minutes, look away to do something on my other monitor/phone, look up to see 3 ready, move my mouse over to enter battle, and it'll kick me out before I get there.
Really need an option for the starter to "ready up" as well. Or other players need to learn not to ready up until it becomes obvious the leader isn't forcing the match. The leader can trigger the fight at any time, doesn't need to wait for the ready up. "Ready" is more a vote of non-confidence that the leader isn't coming back. You ready up to get the time-out so you don't queue into the same room with a leader who is completely out of it.
I've recently gotten back into the harem game with this game. I have Trisha, Meryl, Sasha, Isabel, Elnora and Emily. I am not doing so well in regards to shards, which I need to upstar my girls, and I still don't have a girl for Air. That being said, my favorites so far are Trisha and Meryl.
