2 I think the smallest tp amount for a shard package is around 500 tp, that's about 2000 favor for a small amount of shards 100? I'm not logged in right now to get exact numbers.
3 Thousands of as change hands on the asah daily from the evidence of my own trading combined with the fact that I'm not the only one selling.
4 The asah takes a 30% cut
5 That 30% cut amounts to more on a daily basis than people can earn from favor on a daily basis because of estimated volume
6 Most shards are purchased with real money.
The 99% is an estimate on my part but that the majority is purchased is very sound.
