so...the helper has to be online to be available then? I noticed a helper that I have always used is still on my ally list but doesn't show up anymore so maybe this is why...I also over time leveled and their team was at about 77K power and my set 1 team 1 is now at 82K so I don't know if that makes a difference.
Also I can post my friend ID later after work if a newer player needs the ally, I have about 4 slots open.
