Attack tool multi fleet claiming
 

Currently, an alliance member with "Claim" privileges can only see who else is on a given wave AFTER they have claimed, so it's a bit of a blind claim in regards to who the other attacker is.
Of course one could claim, find out who it is, organize a calc or whatever, and unclaim afterwards if it isn't working out. This seems unnecessarily tedious.

This also makes it awkward for a common scenario, where 2 or more players regularly team up, but only 1 is online at the moment the attack is up and they want to leave the wave open for their buddies when they get online.

One solution would be to add an access level to the alliance Attack page that allows claiming and viewing other claimants, without also giving them full access to edit an attack like it is currently setup.

Would also be useful to have an invite to wave function, where someone could invite an alliance member to their wave within the game through a dropdown.

The attack page does currently allow Claim access to see who has claimed. I think your issue is perhaps with xVx access settings: [Member Status] set to [No access] or other setting not set quite right.
