Introducing champion experience levels
All champions would win experience by winning a fight. It starts from level 0 for unawakened champs or current signature level for awakened ones and goes up to max signature.
Unawakened champions cannot gather experience by being in the team and gain 50% less experience.
When a champion gains a level he gets a +1 signature (unawakened becomes awaken).
The awakened champions in team receive 10% of the champion used in fight with 5% increased experience for each synergy they have with the champion used in fight.
If an already maxed signature champ levels up, you receive a new profile different picture of that champion and unlock shards gathering for him (for new levels he will get a small amount of shards of higher level)
