I do get that your technically correct. Adding it all together, 1k digimon is almost like getting 10k digimoney.
The problem for me is that while they get added together. The difficulty Is in no way similar.
1000 isn't even currently possible. So I don't see 1000 as a first goal or primary goal with a 10k reward.
I see 1000 as the reward for pushing from 900-1000. Which is harder than any of the others since you just have to wait for new mons to appear and snag them instantly before they leave and even then, it is gonna take probably months. This is a hard goal!
And this goal only nets me 1000 digimoney? Not worth even thinking about. Wait til it happens? Sure, but no investiment. No desire. I am gonna get more digimoney from logining in and not playing over the months it takes me to get the 100 digimon.
So as a reward it fails. I think 3k would be a fail too. I want at least 10k! That would make me excited. Make me want to play. Earn that 10k!
