I wouldn't change the dragons; I would just tweak them a bit and give the upgraded version the "Ethereal" ability.:cool:
I haven't found any other use for "Ethereal Dragons" other than as a shield between enemy troops and Death Knights... they even cast spells poorly! I was besieging the Castle of the Academy of Magic, sent a dragon to reduce the damage of the Titans, but they couldn't even do that. After the dragons attacked, the Titan's damage was 40-41 instead of 40-50! And they also shamelessly hit them with lightning, the bastards.:mad:
Personally, I don't consider "Ethereal Dragons" in their current state to be level 7 units. Even in Heroes 3, they didn't look that bad, but now they have turned into a very awkward and expensive unit. They desperately need "Ethereal"!:smile29:
