Um... you do realise that you're playing a MMORPG, right? They're grindy in nature.
Also, in order to get every item in the event... all you need to do is login and talk to 3 NPCs. That is it. You are given a MGP card worth 30k MGP, which is more than enough for you to get every item in the event. I don't see where the issue is. They are literally throwing these things at you and you are still not satisfied?
