Yes it's very useful! Thank you so much for your awesome work
Well I don't think it matters that much that the dragon is just disappearing when the dummy missile is killed by trigger but yes it could be nice with some special effects when it dies but it still doesn't matter that much. I don't think it will be possible to make the lightning dragon as a missile instead of a dummy unit because the spell is so much advanced and it will be very difficult to make the spell work perfect without bugs or glitches if it's used as a missile because the spell works like the Shockwave-ability but it also stuns and slowing enemies that where hit by it and the spell works perfect how it is now.
