I also still do the free WOF spins as I am trying to reach to 100k RP mark; currently only at like 44k so it will take a long while to get there though. But as you say, it doesn't take long and we can always dream of winning the top prize also when spinning the wheel.
Be realistic. Considering you need another 56k RP to reach 100k RP, it doesn't make sense to do it with WoF free spins. It will probably take several years to reach 100k RP only through free daily WoF spins because the most common prizes in spins are either 10 lottery tickets or 10 RP, while prizes such as 100 RP and 1000 RP are pretty rare.
Yeah I know, but I hate just loosing these RP and there is nothing else you could really do with it. Activating it for some prize boost in base price on the free rolls also is not interesting as the amount you get is close to nothing. Open for other options though.
