Rushed Town Halls and War Matches
Rushed Town Halls can really mess up a war match. Why not set some limitations to when you can upgrade a TH? For example, if you're TH9 you can't upgrade wizard towers to level 8 until you're TH10. Why not reverse that and say you cannot upgrade your Town Hall until you reach a certain number/level of defenses?
This idea was discussed in our clan chat after our most recent war match. If you look at clan tag #882VYYG2, checkout the player profile #JQ2UGCCO. This player was ranked lowest in the war match, but he was a TH10 with inferno towers and maxed troops. His other defenses were extremely low or not built, keeping his ranking extremely low. This player was matched against a low level TH8 in our clan.
Those that have rushed Towns Halls will not like a change like this, of that I'm almost certain. But I think setting peramiters around when you can upgrade a Town Hall will be extremely beneficial in the long run, especially for the serious players that get frustrated with uneven war matches.
