If you put together a package with a discount for all blessings for 7 days and even cheaper for a month, I'd likely buy turquoise to get it if it was well priced. Once I had bought turquoise and it was in my account, I'd probably use it sometimes.
That was certainly my experience in Lord of Ultima. I know a lot of former LoU players who were happy to pay a smallish amount every month because of this and because there was a mana system limiting "turquoise" use and that meant it was impossible to pay to win. Better perhaps to have a lot of regs giving you a few bucks than one or two at best whales scaring everyone else away?
One other unrelated suggestion from the same game was an actual way for an alliance/tribe to win, come 2nd, 3rd, meaning regular new servers and so motivation for players not at the top of the ranks to learn, form bonds with players and look forward to the next server.
