Maybe a way to get money

[Mourning Wood]

IMO If you add credit's as an incentive it just becomes a money grab. It should be completely voluntary and done by people that just want to help and that's it. Know all those annoying ads on mobile games? This is basically what it is, if you add credits to the equation.

But that's just my opinion.

I think its fine because its optional and it would be helping the server I dont see the problem but I respect your opinion

I don't think I'm really explaining it properly, it's pretty hard to. Basically if anything ad/money related gives you a form of in-game currency, it's sort of becomes compulsory otherwise you can't really keep up with others. Players would have to grudgingly go through all the ads just to get those free credits. It's just like any other advertisement "Do this and we'll reward you" and if you don't do it you'll fall behind, so we're kind of forcing you to do it.
It's really hard to explain but a majority of incentive driven advertisement campaigns end in a really annoying experience.
But everyone has their own opinions right? That's just my personal experience on the matter.
