I don't like this idea even a one bit ;p 5k isn't that much, u can easy get that much from NPCs, or wild pokes, even if u're a begginer.
If staff will change Saffari to open, unlimited in time, acess wichout changing in spawns we can expect ton's of shiny scythers, tauroses, rhyhorns, kangas etc. in no time.
Palayers from That Other Game, would know what happened, when Saffari was open to free access during just one weekend event.
