Anniversary event going on right now. Catch the Ash Hat Pikachu and oh gee wow, a "Sale" on special items if you want to call it that.
You can buy an Anniversary Box for the low low price of 1200 pokecoins. Lets not forget that we're currently still getting only 50 coins a day from gyms when we get knocked out of them. in that box, you're getting 6 incubators, 6 Max Revives, 2 premium raid passes, and 20 ultra balls. You can buy 6 incubators already for 900, and the 2 raid passes for 200, everything else I can grind out at stops. I'm not really seeing the awesome deal here to make me want to blow my money on it. Now if they was throwing in 6 raid passes then we might be talking about a deal here, but I'm just not seeing it with the current in game economics.
Raid bosses are kinda cool, but yeah, anything level 3 and above you're going to want help with the battle. Rumor has it that Legendaries are going to be coming in the form of Level 5 raid battles, and we might see those sometime after the Chicago event. that's going to be a ball breaker to knock one of them down.
