At the moment it seems like torrents are prioritised by size by the indexer (Kickass Torrents in my case). This often results in torrents being selected that have few, if any, seeds. Tried playing around with size limits to get around this but that had very limited success. Adding restrictions to look for certain group releases that would typically have lots of seeds has helped in most cases.
Having finer control over how the indexer selects an appropriate torrent would be great. I’m sure there are a million possible options but being able to tell the indexer to prefer seeds over size would be a great start.
