Earthquake spell balancing and revenge list

As a player of 2 years plus I think I am experienced enough to say that the earthquake spell needs some rebalancing , I have no problem with 4 eq spells taking down any level wall but the radius is far to large at 8 tiles, most times this spell is able to take down 2 to 3 sets of walls and seriously compromises the effectiveness of most base designs, since there are not enough walls for base designers to create adequate anti eq bases I would like to see the eq radius reduced from 8 tiles to 5 tiles to allow a more balanced protection against this spell.

Also on the revenge list would it be possible to have forward/reverse buttons similar to the war screen to allow you to scroll through the revenge list instead of having to come out of the list altogether and reenter it in order to see the next base.

Thanks
