Ok, I may be confused with tier and tech and level and whatnots... So, just to be sure:
Procurer is tier one and I should not touch it. I woud be able to fly one next Wednesday.
Retriever is tier two and is good. I would be able to fly one next week on Sunday.
Covetor is tier three and takes a godawful long time to get but is really worth it in the long term.
So, I should stay clear of the Procure?
