100% win record
Gryphonkit, my wife, likes it.
Granted she has a 100% win record in alliance war as a solo ( might based matchmaking has some loopholes).
Loot
You do give up significant loot since 9* titans are much better loot than 1*-3* ( you need first place on 5* / 6* titans to even get 4* ascension items).
