This is worth implementing. Squads exist, their system is being used very regularly and actively, and obviously they apply the same application system as groups.Shouldn't be forced to wait until the player comes online. Should be able to invite the player using his/her account name at any time. It's pretty much worth developing.
Why not? Everything is pretty much explained. I would like to see a such feature on the server. I am supporting your idea as well.
