Idea For Revamping Allies & Guilds

First, eliminate the ally list. Your allies are your guild mates, but that has the problem of not letting you have as much of a chance to find a great guild or borrow up if your allies are all lower levels. So, you are temporarily allied with (can borrow heroes from) the last 6 players you have attacked in the arena. This will encourage players to attack up in the arena to get access to those heroes and will let you look at their guild status to invite them or request membership. It also gives a way for the guildless to still borrow if they don't want to be in a guild.
