R/E Build needing some help in atribute pts distribution

Hi guys, ive been playing my ranger for a while and ive been sparing to buy the new 15ks druids armor when it comes out. The thing is i am not shure of the runes i should really use so i was hoping for some help in that department. Right now im only using minors but i wanted to ask if i should put major or superiors once i get my final armor. Here's how my build is now:

Expertise:9 ---- 8 + 1 (minor)
Marksmanhip:12 ---- 10 +1(hat) + 1(minor)
Wilderness Survival:10 ----- 9 + 1(minor)
Beast Mastery:4 --- 3 + 1(minor)
Fire Magic:9

I play mostly tombs with this character, here my skill rundown:
Conjure Flame, Kindle Arrows, Tigers Fury, Dual Shot, Poison Arrow, Distracting Shot, Frozen Soil and Pin Down.

My idea is to make a good solid damage dealing ranger with some answers for other problems like stoping a rez or a running monk, but my main function is to sort out a good amount of damage. From what i've heard ppl say a good ranger has got to have very high expertise but ive failed to raiser it up more since i also use wilderness survival and i like it alot. So hope some one can tip me in the right direction with how to manage these atribute pts and what runes to get. Thank in advance

any help pls?

Make your Expertise 10, then use a +1 hat and a Superior Rune of Expertise to bump it to 14. This is considered a must by most Rangers.

I honestly don't know what else I can tell you.

mmm ok so what would u think is best:

BM: 4 (3+1)
Marks: 12 (11+1)
Wild: 8 (7+1)
Exp: 14 (10+4)
Fire: 7
Using only 1 sup expertise

Or:
BM: 4 (3+1)
Marks: 12 (9+3)
Wild: 10 (9+1)
Exp: 14 (10+4)
Fire: 8
Using this way a sup expertise + a sup marksmanship.
