There are plenty of Rangers on Melrassar in my Ice and Fire game, I'm strolling through using Rangers, Elves, Avengers, Scouts and Rune Wizards. The items I have make them stupidly overpowered :-
Telescopic sight -
+100% attack of shooters
Siege Crossbow -
+30% damage of bowmen
-1 initiative of bowmen
-1speed of bowmen
Dragons Quiver -
-10% leadership requirement of bowmen (doesn't work on the scouts)
All bowmen have 1 charge of dragon arrows at the start of combat (I spit on your black dragons!)
Elven Crown -
+1000 leadership
+1 morale of elves (doesn't work on the scouts)
Belt of Strength -
+25% attack of allied troops
They all have sniper ability so they can stay right at the back of the arena, at the start of combat I just cast precision and unleash bowman hell! I ditched the slingers and the lvl 10 bowmen ages ago and the damage I dish out is obscene... I'm just in the Cave of Mysteries now and I'm winning most fights in two rounds with no losses and without using the spellbook or rage skills
