A few ideas to make MPQ less boring in the long run

So here are some few ideas which could make the game less boring and more fun to play :

1) Have the player choose which mode he wants to be in : Simple, Average, Hard, Deadly - the harder, the more prizing. You can change mode whenever you want.
2) Have limited edition characters for special events. You could get all the covers in an event marathon, but with nothing else to be done at the same time. There could be several formats. And you could even pay for entrance, but the prizing would be appealing.
3) Equipments for the characters : different ones and some could only match some characters
4) PvP with new chars, that would be maxed, but you could test. A sort of teasing. Cool prizing also.
5) Automatic deleting of covers you already have in the prizing structure
6) Higher prizing if you win over bigger teams
7) Test tournaments : you can test a maxed character so that you can make yourself a good idea about how good/bad it can be.
8) Include a wider variety of tournaments in Seasons.
9) Tournaments based on a geographical area : America, Europe, Asia, Africa, Oceania - Brackets are built according to your IP.
10) More 2* and 1* only tournaments, with new characters to be won during these characters.
11) Subscription program OR if you have spent a certain amount per month, have unlimited lives and can play all the time if you want to.

There are several thousands of characters available at Marvel. So there is no problem with creativity.
