Not impressed with this event. Won't miss it when it's gone.
In game chat is good, but how much chat can you do in a 5 minute battle?
Plus, factor in 3-4 app crashes into every 30 minute war; that leaves very little time to scroll thru your arsenal to find the items you 'guess' will be adequate to achieve victory.
Agree that 10 minute battles might be better.
Also like the suggestions about assembling or packaging forces (for deployment) ahead of time. If not, there would really need to be improvements on scrolling/searching.
