Sentinles and New Lordaeron are stuck with alliance forever also. Personally I don't like the notion everyone in alliance can betray. I think it was a bad idea to add betrayal path for purple tho thankfully its useless since rouge alliance is a meme. Some alliance members are 1 at least needs to be held responsible for the alliance, game just become chaotic and eventually Scourge vs Legion since as soon alliance knows they are gonna lose the 6v6, everyone just instantly betrays. Making the alliance comeback not possible, which is a shame since alliance comeback games are most interesting and a resilient alliance always makes for interesting games rather one who instantly breaks into nothing as soon as something goes wrong. I agree on Muru tho, the +1 is wasted since you have to use upgrade instantly if you want to survive.
