Maybe a nice option for new players, but rather little chance of introducing this thanks to older players.
Some people would just get too many crystals for free
If you put in all that time, why not get all the shiny things. Seeing your stuff will inspire other people to want stuff, maybe even faster. Even if you had 10,000,000 gold, that'd 50,000 gems , they sell gems in stacks of 8000 and price things over that so it's even then it's not really THAT many gems. Especially as a reward for the time spent. It'd be good for the the people that have been around a while too, thanks have an oddessy event on us champ.
