I currently have a 5L4 Shar Melee Ranger specced:

42 Pathfinding
35 Stealth
36 Blades
39 Celtic Dual
AT Bow

Was wondering what would be recommended for RAs:

Mos2,PD3,AugStr3,Purge1,IP2
Mos2,PD3,Tough3,Purge1,IP2
Mos2,PD3,Mop3,Purge1,IP2
Mos2,PD4,Purge1,IP2
Mos2,PD5,Purge1
Mos2,PD3,Purge2,IP2

Thanks.

I actually like the 3rd one down. I dont play a mele ranger, but IP2, Purge 1, and PD 3 are a must have. Option 3 gives u all that as well as MoP 3 which is very nice. I would STRONGLY reccommend going w/ MoS 3 at some point. Being an assasin hunter the first thing u have to do is find them. MoS 2 is not that big of a bubble to find other stealthers.

I don't know your playstyle but when you want solo RvR Purge II is a must have - when you are stunned your DPS drops to zero.
I would go for MoS III, PD III, MoP II, Purge II, IP I
If you are group stealther switch Purge and IP.

Yah, I guess i'm just old school in my thinking, but I always say that Purge 2 is a waste of points since all you get for 10 points is a 5 sec reduction on stun/mez. I can see it for a NS or other classes but on my ranger I have so many places for my points to go that those 10 points are to precious to spend on 5 seconds. Instead get really good at timing stuns. Only class that gives me trouble on this is reavers and thats because they just love to throw a little dot on u b4 they get to u so u can click purge and use it on a dot. I've just learned to wait a sec on a reaver and hit it a little after the battle has got started. Purge 2 is nice, but that is alot of points to use when you could increase other areas that will have more impact.
