If everyone is actually going to do this, then I strongly suggest changing something in burrow to let the SoR target a burrowed unit. This way the whole SoR + Fate Egg potential remains. Although personally I think it'd be a interesting buff if when affected by the SoR the fate egg's hatched counterparts also have the SoR benefit. As in if it hatches into a Mind Flayer while having the SoR effect, the skill costs 0.
