Casting Delay and Times

[Lezowski]

if you really wanted to check it, you could have found it yourself. ;-)
healing drones do 126-127 ( hero type ) damage at normal attack rate ( 1.00 ). upon return, 80% of the damage dealt will be transferred as hitpoints back to the air ship.

Why need add this to the tool-tip? You can maybe round it down to 125 and 100 hp healed to make it simpler, though it is affected by armor. I also agree with tc that the casting time for healing drones should be removed like light tank's repair.
