Oh wait a minute, are you talking about war of the ring or SBG? If its war of the ring then i have no idea if its the skirmish game then here are my words of (little) wisdom.
If you want to use drar you have to use his best mate murin too, they cost 150pts altogether (which is alot) you'd be better off with haldir. Fellowship boromir is a nice model but needs an elven cloak so that wraiths can't manipulate him, but captain of the white tower boromir is very good, but very expensive. Faramir is a great mid range hero, he will killa model or two more than cirion or madril but ultimatley he's the same sorta hero. Now onto the human rangers: there is a 33% bow limit on all warriors in all armies, and every ranger comes equipped with a bow, so you will only be able to use 8 rangers and to do so you sacrifice the WoMt. However there is an army called the grey company which does not have to follow the bow limit, instead they must include 1 dunedain or ranger of the north for every 4 regular rangers. The grey company can ally with gondor
If your wondering what a dunedain/ranger of the north is, its just a normal ranger but with a point of might, will, and fate, so it is classified as a hero. Allying in some grey company is great because it:A: Provides loads of bowfire
B: Provides lots of cheap might, meaning your leader can waste all of his might on killing foes while the dunedain call all the heroic moves
C: Provides spears
D Also gives you access to aragorn, the twins, halbarad, and last but not least: Arathorn
