not sure if it counts as whaling (especially since it took me over a year to reach the point where I'm at), but i'm pretty much buying my rainbows and nothing more...
which is why i'm hoping black friday gives something good... with at least 5 rainbows of each type, i really don't need to go out of my way to get more unless the deal is far too good to pass up
and if we ever get to use leader medals for those guaranteed gold tickets, the deals would REALLY have to be epic for a smart player to buy them (cause you'll get fed rainbow medals a lot easier)
