While this of course COULD be a huge money sink it doesn't have to.
Mobage has a choice at this juncture. Do the above and slowly kill the game.
They could also increase droprates of cards to compensate for the higher requirement. They could also make it possible to complete Evo cards by simply playing a lot and "grinding". Money should just get you it faster but be supplantable by time invested. They can also make each individual card cost less so players buy more cards but spend the same amount (or less per player but more players spend).
Ball is in Mobages court. They can either do this properly and make this one of the better CCG out there, or drop it entirely and doom it.
This also will likely allow for the inevitable combiner cards to finally come to fruition! If they do this properly without the money sink, it could be a great addition, but they MUST do this right or many who are already on the fence (like myself) will see this as just another money scheme and be done entirely. I've cut back while on vacation in my spending both in time and money, and will find another hobby entirely if they fail with this.
All it takes is a week or two away and going back is not so easy when you realize how useless your deck has already become. Then again, simply knowing this automatically makes me not a part of their currently "intended audience". Hopefully they do the right thing and lure many back who want to play this game because overall I love the collecting element. They really need to announce trading as a thing too, and perhaps with the new card type, they will finally, if nothing else, for the current cards we have been collecting. I still believe an episode "rerun" wouldn't be a bad idea either for those who missed out, for a lesser price since the cards aren't worth nearly as much now in terms of deck power.
As several have pointed out, the ball is in Mobage's court. What they do here will either save or completely break the game once and for all. Make the right move Mobage! (my hopes aren't very high)
Just a thought but with these new evo cards coming does that mean that we will get new weapons aswell?? more to the point do they upgrade aswell (joking), if so will they also be a further drain on our wages
i just posted on another link called PLEASE FOR THE LOVE...... if u read that basicly how it showed work if they follow GI JOE which it looks like they are going to do have a read as cant get link to work
Actually the evolution cards apply to certain cards that are captured when you defeat a boss in the upcoming events. This has nothing to do with any of the other current cards, but it is not going to be an extreme money drainer like most of the events.
