Can we get a phone/Ipod version of this where its connected to the cloud but where we can use it offline? I know it'd make it easier for but also more fun..... brilliant game though, so far on R16 soon to be R17
maybe in the next patch, when you upgrade by using shift and ctrl, it should show how much DPS you are gaining from doing that, this would help understanding which heroes are worth upgrading past getting all the skills on the heroes.
