Flare, you have a lot of boosts for units and towers, but what about a boost for the hero? I want my hero to be able to jump barricades and cross lanes, to help me deal with those pesky trap towers. So I got to thinking… What about wings? You activate the wings for a brief time, and you’re able to jump barricades and possibly even cross lanes, until they’re shot off.
But then I also got to thinking… Everyone already wants a buff to the Shield spell. What if you made /that/, the elite shield spell? While your shield still has health, you’re able to fly over things. This would give the Shield spell some usefulness again, and also keep the wings from becoming OP. like, if you could have 3 spells /and/ the wings, the hero would be able to tag all the towers while his units dealt with enemy units. But I think that adding wings to the Shield Spell as an elite boost, keeps it from being OP, makes the Shield spell relevant, and fills a vital niche of being able to take down trap towers.
