How about one month free..BUT whenever one is in the TA ONLY,it does NOT count torwards the month trial..AND,and this just came to me..The D.A. costs 1/2 of time torwards the month..that may be a bbit much..
but the TA no time cost torwards the month free, I think, would go along way to getting someone half way decent and wanting to stick around..They get killed in the MA's and hey go train in the TA get better,then go fly around the MA's.We all know time goes very fast in this game.
And maybe the hourly set time,instead of a flat month,would better utilize this scheme..
