I think that Bill Ferny isn't fit for Isengar as scout. Bill Ferny never fought for Isengard. Also, Bill Ferny is one of the least favorite hero in mod.
i have idea for new more fit scout hero for Isengard:
MauhurMauhur is a small character from the book and movie. He was a standard hero in the old version of edain mod. But now he is only as summon for Ugluk on level 10. I think Mauhur is more fit for scout role in Isengard. After all, he is uruk-hai from Isengard. Bill can stay in mod on special maps or something like this.
Mauhur abilities:
Level 1: Toggle Weapon - Switches between axe and crossbow. Mauhur has crossbows in old version of mod. This will be something unique for him. if I know no one hero in edain used crossbows.
Level 1: Gather ScentMauhur gathers the scent of the hunted enemy.
Mahur and his elite scouts have 200% visition range and 25% speed for 20 seconds.
Level 4: Man fleshMauhur smell flesh of enemy hero.
For a short amount of time, the closest enemy hero will be uncovered.
Level 6: Mauhúr's reinforcementsMauhur temporarily summon four elite scouts with axe.
Level 8: Hunting trapMauhur set a Hunting trap to selected area.
If Enemy unit and hero step on a trap, gets medium damage and -15% move speed for 10 seconds.
Trap can have this design:
Of course, Ugluk needs a new ability:
Level 10: Escape from encirclementUgluk and his guys fight to the last man and trying to get out form encirclement.
Ugluk and uruk-hai units nearby are immune against knockback and can't be trampling for 15 seconds.
What do you think about this idea?
