Why not have an all-in riskier raid option to spice things up.
Since people like to complain about lack of ascension mats.
Those who are willing will enter their hat into the ring at the watchtower.
Cost of entry is a SINGLE x 4* or 3* ascension mat that will only be refunded if you win the raid match. And perhaps a minimal (?) gem payment.
(Is this any different to paying 100 gems for the now-discussed raid challenge or is this more acceptable @Brobb)
This special raid option is only available once every two months per player.
(This is important from SGs point of view, otherwise it would be too easy for players to get mats)
Browse opponents and search/filter for ascension mats they have.
Two players must agree to the match, as they want what the other is offering.
A raid battle or match begins. Player A raids first. Player B raids next. Whoever wins or defends (or one of each) two raids in a row wins. Whoever wins takes the other person’s mats and their mat is refunded.
The loser has an option to revenge two months later but the opponent may put a different mat on the table.
Revenge will have a new meaning.
Perhaps this is an old idea? Or superceded by the raid challenge.
