Yeah it seems like a while but most people I know can only go on the weekends as they work full time, so at least this way they have more than one weekend to try and find one. xD People were already burnt out after the birds and having to stress over getting everything during the limited time, I reckon they would get sick of it pretty quick if they just kept releasing legends with short time periods.

I didn't even manage to get Zapdos this whole event despite being at a uni every day with 8 gyms in sight... The group here managed a total of 4 Zapdos raids and I couldn't catch any thanks to RNG. xD Most of the legendary raids started at like 6.30am here for some reason, and ended before anyone even got to uni. So dumb. :/
