Dont slow it down
Firstly, dont slow it down. For most people its slow / hard enough. Its only the real top end players that find it to easy.
Revives
I think the suggestion about auto revive is a good idea. Particularly since you have to have a breaker in order to progress to the screen that allows you to revive hero. This means that as it stands, even if heroes are revivable you might not be able to do so if you are out of breakers.
Another option is to get rid of cooldown altogether, but give us less revives so we have to be more careful about their use.
Invasion Market
Whatever happened to economy of scaleā¦ why do we get lower value the bigger the item. If I am using points to buy some breakers either standardise the price per breaker or make the larger ones better value (same comment re all items in Invasion market).
Guild members listā¦
Not a big dealā¦ but i would have expected to be able to filter my Guild members by invasion ranking from the Guild page (i.e. in the same way as arena and colleseum).
Power Ups - invasion tiers
I agree with comments on the 75% slow down buff. Sometimes its too much (especially in absence of auto cool down). Either reduce it or stagger it.
Absence of power ups in breakers
Not everyone has fabulous shield heroesā¦ and even if they do once they are KO bosses can be a real challenge. Especially in view of comments on cool down. I think the power ups available in tier fights should also be available in breakers. For the most part they are not huge power upsā¦ its the shields that i think are needed most.
