for some people it is a long time, just because you have way more time to play this mmo than others and feel less satisfaction breeding godly pkmn fast, doesn't mean others who dont have alot of time to grind have to suffer from your desire for a difficulty increase
there's a reason why breeding is easy and should NOT be compared to your runescape reference. for instance, pkmn are worth atleast a hundred times less than a partyhat was back in the early days (keep in mind, we're still at ALPHA stage). also considering the amount of pokes we have to breed for each competitive tier and pkmn with different sets. when you've bred and raised around 100 competitive pkmn (i dont even have 50 and im from 2012 lol), you dont even get close to the value of a partyhat
soon (2018 (tm)) there will be more content to grind from like battle tower, legend dungeons and all that crap, and you suggest making breeding harder when we need more pokes to use for the soon added content? does that even make sense?
