If you played spec op 2 or 3 you would have seen that the hero deploys make you deploy characters that cost 58-90 CPs. I think Playdom is "forcing" us to buy characters.
For example, a lot of people don't want to buy BP but now they have to if they want to get Magik. Another example, a lot of people didn't want to buy Pheonix but they had to because they wanted to get Emma Frost.I think that's not fair because they totally nerf those characters afterwards, but this is not the subject of this blog post.
BP and Pheonix are mildly popular chracters and I think that Playdom is trying to get people to buy the New characters like Rogue or Gambit and the Old and not-so-popular characters.
Playdom are making the game harder for people that don't buy gold, and if you think I'm wrong , comment below.
