You start a search hoping for a good match up only to wait over a hour to get matched.the clan you got matched with is a totally unfair match-up.
What if you could pay a few say 25 gems to next for another match up ?
Only the one who started to search can you have like 5 mins to decide if you want to next. And after the first next and every next after price dobbles.
First 25
Second 50
Third 100
Forth 200
Fifth 400.
And a cancel war cost. Just the same price.
This would work like the reduction of shield in regular matches if you want to attack while shielded.
Why would super cell include this. As a better fix to the issues of match making. And heck I would spend cash for gems to be able to do this and so would others.
