I think there should be a favorites button, for players who don't use Facebook . Say you squad with someone who you like , but say they are already in a clan, so they can't join your clan, and they don't use Facebook, and what are the odds you'll run into eachother in battle? If there is a favorites button, you can invite them to squad whenever they're on.
I don't like the Enemy Power Indication because it is unfair for the enemy. For example, if a player on the red team has a maxed out Orkancilot, and it tells you he is way stronger than your bot, you'll stay away from him right? Then Mr. Orkancilot won't get any kills because everyone's avoiding him. Then he'll be dropping down because he is losing league points, and he will be in lower leagues, continuing to drop. So, the EPI might not be a good idea.
