This is a really lame excuse, and I seriously am tired of it. Being an MMO doesn't mean everything has to be extremely rare that you never even see it in your lifetime.
If you want to press W and S and press "Run" for 10 hours a day to see 2 Dratinis (or anything as rare) a day, suit yourself, but in my opinion, this will only discourage people from playing and encourage people that want to play to find methods to bypass the grind (ie, scamming, botting, RMTing, etc), which, by the way, are all very common things in MMOs with lengthy grinds.
Extremely rare that you never see in your lifetime lmao ? IF you actually spend some time to actually HUNT for the pokemon instead of posting a topic crying about it maybe you will get to see it once. And no this encourage people to actually put time into the game to HUNT for the pokemon that they love. And no because it's an MMO is not an excuse it's a fact and that's how MMO should be. What's the point of everyone having a perfect dratinis in the first month of the game ? What's the point of actually hunting for rare pokemon anymore ?
Yeah because finding 1 rare Pokemon after 10+ hours of running back and forth only for it to be shit is REALLY ENCOURAGING. I sure do love being rewarded for my GROSS amount of time spent looking for ONE POKEMON that is REALLY BAD.
