Line of sight placement for high flying units. Such as Phoenix (in Stratos) and mosquitoes in HA Gribbles for example. Why is the line of sight sphere placed so low on the floor? Just little deep or hump on the ground and you get the “you can’t see the target” message? It can be right for some mobs like slime, little crawling critters, etc. This can be very irritating time to time.
