Our guild, Thrawn's Renegades has 11 soloists (and counting).
We have an 18 hour registration period, during which everybody is encouraged to send one toon (the weakest) to score a zero by hitting the guards (side pigs).
The actual raid lasts about 15 mins, yes, many pre-load, but nobody registers until at least 5 mins after the raid opens.
For soloists, we have two additional rules and dynamics. First, no auto during pre-load time, only auto when the raid opens during the first. Second we rotate the top three -- only three can solo, and we rotate basing in player nickname. I keep the order of things on a google doc available to all guild.
I dislike this method, but better than nothing. The rotation evens the peace among my soloists. We are eagerly awaiting EA's better resolution and, of course, some Chewy shards.
