It’s another example of a fundamentally ‘mean’ economy. Sure, free is free, and sure you get the milestone by ‘just playing’. But the telling point is whether the game is GENEROUS in celebrating your achievements.
Killing 75 Titans is an achievement. It shows commitment to play the game for that length of time. And the reward you get from the game to celebrate your commitment to it? Less than what you can get on a daily basis for something as arbitrary as watching an ad.
I think the game should show more generosity, especially in rewarding significant achievements (like finishing all the map levels, reaching lvl 30, killing 75 Titans, etc).
There is no cost to generosity, and it is rewarded by loyalty. Being mean in your economy, however, can only generate hard feelings and disinterest.
And what I continue to be amazed at is quite a broad acceptance by the established player community of the lack of generosity… it really is an odd form of masochism.
(Sure, I get the game balance arguments… but more generous ONE-OFF rewards for such long term achievements is not going exactly going to swing this, is it… and just shows the receiving players that the developers actually care about their efforts. A nice thank you instead of a dismissive ‘whatever’).
