Make it so when attacking people can only use a team that is at most 130% power of their defense team’s power.
For example if someone’s defense team is 100k then at most whenever they are attacking they can only use toons whose total power is 130k, this way if everyone else is using toons with a total power of 1 million for their defense team then someone tanking with just a single toon with 100k power will have no chance at winning against those teams, but if they are also using 1 million power on defense they have a chance.
I really don’t know why something like this wasn’t implemented within an hour after this new arena went live when it was obvious what people are doing, we are almost finished with the second week on our server and people tanking their defense have a clear advantage.
