Well i'm 80 now

i'm a str hybrid acrher and my build for now is lightning/cold 60 and fire and bow 80, But when 90 cap comes out i was planning to raise my bow and fire masteries levels to 90 and keep lightning and cold at 60, but i debating on that... should i dlvl my cold and boost up lightning to 90 or keep it the way i was planning to? Your guys thoughts.....
