I don't understand why people constantly complain about things.
If you are free to play than accept that fact the game itself is free it's not like Storm 4 which will cost you an upfront cost in saying that you can still earn Tendo without spending real money go hit the Tendo treasure 400 times, don't want to do that? just wait it out to buy the remaining fragments. This game is an MMO it's updating constantly there is no reason why you should expect everything to be earned so easily otherwise there isn't that much point.

You can argue many things about this game a the devs but at the end of the day you're playing a free game that is constantly expanding work on other things and be happy you got that boost to begin with.
