I do think they need to get name changes under control - lock them down after maybe a week's notice, then charge gems (as in their other games) for further changes. I think names should also be unique, but that's a smidge harder to enforce fairly ex post facto.

I'm not sure how I feel about locking down a war lineup for the duration of an event. Yes, some people will be switching up frequently to gain an advantage over their targets, who may also be switching up for their targets, and so on... but so what? It makes scouting an unreliable proposition, which isn't awful, just different.
