I find balistas are essential in GE without rogues
Edit: remind me, what's the max number of friends? Was it 141 or 144?
Edit (2): nevermind found it
You can send invites as long as your number of friends is under 80. and you're able to have up to 140 friends at once. Keep in mind that you won't be able to send new invites until you're below 80 friends again.
I guess it says 141 on Noarsil because it's including me
Edit (3): After eliminating everyone that hasn't aided me in 1 week, I now have 102 friends including me
