Elvish Lord/High Lord

[Araja]

I tended to overuse him just because he has the most awesome attack animation ever

Playing HttT on hard for the first time (beat it on medium some time ago, won a few other campaigns on hard so decided to go back to it) I managed to get Delf killed in the first scenario twice running.

Same problem as other people: he is so much more powerful than anyone else I have at that point, I get sucked into overusing him to save them.

I, personally, think that Elvish Lords should have a weaker melee attack than Heroes - I mean, they arn't the real brawny people, by the look of them, unlike the Hero.
But I think 70% in forests is fine; I always picture them using less armour than the Hero, or magical protection at least.
