Time for another rant about another spell that is in desperate need of some changes. I have not seen Heavenly Dome used by anyone in months! It is now a completely irrelevant, expensive and boring spell and has been left behind in a previous patch. I'd like to kick this off with a suggestion but please feel free to add below any thoughts on how to improve this often overlooked spell.
Perhaps activating it could cost health instead of mana... A 10 health activation followed by a 10/sec drain on mana. Couple this with adding back the healing ability of the dome but reducing the heal to 5HP. That way, triggering dome unnecessarily would cost you dearly but successful blocks would heal and not be so mana-intensive as well as blocking those pesky feet shots we all worry about.
