RE: marvel avengers alliance
Explain how? Functionally it's like regular pvp, only with reduced rewards, and level capped.
Your rating (Silver, Gold, Diamond, Vibranium and Adamantium) is based on two factors:
1. Your points (you gain points for winning battles and lose points for being defeated)
2. The total number of attacks you've made.
In order to go from Silver to Gold, you must have enough points to be in the top 30% AND have made at least 10 attacks. It doesn't matter how many points you have, if you have not made those 10 attacks, you will never leave Silver.
The number of attacks you need to make to unlock new rating rises with each tier, and the number of points you need to remain in the higher tiers likewise gets higher and higher.
