Champion limits in Alliance Wars
I may be alone in this, but I feel like alliance wars are becoming boring due to always facing the same champions in the opposition's defence.
In order to make things more interesting and add some variety, I think it would be interesting if a champion limit were to be introduced so that only 2-3 instances of the same champion can be added to any 1 map (a map being an alliance war battlegroup).
Some nice side-effects of this limit would be that it would make players think more about node placement - for example, rather than just placing Mordo's everywhere, they would need to think about which 2-3 nodes would be best for the 2-3 Mordo's they are allowed to place.
It would also cause players to think about other, less obvious defenders, to rank up based on what nodes they could be effective on.
A third bonus would be that it would add a tactical element, in that alliances would need to communicate and work together to determine which players should place certain champions up to the limit, based on their masteries, PI and signature levels. They could also use this limit to help determine which players go in which battlegroup.
I would like to see a 3 champion limit per map/battlegroup introduced, with this reducing to 2 instances of a champion for the highest tiers. Beginner tiers would be exempt due to new players having small rosters.
