I was in a similar situation waiting for friends. I let them talk me into starting over from scratch on thier server(Karana). After I pounded to 53 solo (they were too busy Raiding to help PL me lol) they all of a sudden decided to restart new chars from thier level 60s back when 60 was max. I as like ok, I guess I can work on AA for a while... so 1 kill from 54 I turned AA on 100%.
I became a Griffon Fear-kite specialist. Filtered out all but Red and Dark Blue mobs. Knowing where those Red mobs where gave me pretty good idea how far the next griff was based on where they stacked up comparatively to those Stationary Red cons. Its amazing how fast we can kill Griffs (collecting a ton of meat and foraged plant shoots in the process... ie big bucks) per hour...especially with a KEI and occasional Haste. My gear was kind of sorry even for Bazaar but by the time I was leveling again I had the best Bazaar gear one could buy at that time.
I got general (run3 and regen3) then started banking AA points for when I dinged 55 and 59.
I decided that getting EQ/AM3 and max archeries done asap was the best way to increase my damage which in turn would increase my desireablility for groups. For Arch I put all 12 in Combat Fury. Combat Fury gives you the chance to crit with both melee and Archery. It provides a significant increase in crit power with bows at level 3. I proceeded to save the points for EQ/AM2. It took a few months, but when I started on XP again I trained CF3 at 55 (was still melee but darned those crits were nice) and at 59 ...boom i had EQ/AM2. After that I leveled to 58 solo in JPF killing Snakes and Panthers... I grouped LDONs till 60 when I went to solo in Fungus Grove killing shrooms (the place was a Ghosttown) where I quickly finishied off AM3 and increased my grouping desireability a bunch.
After that groups were plentiful and I alternated between Leveling and working on Fury of the Ages 1-3 at the appropriate levels (more crit power). Then went to 65 when 65 recently became new max level from 60 grrrr.
Anyways It can be done, but it is slow solo. I decided to stay at 53 to grind rathr than a higher level where lucrative grouping places opened up like PoV55 and BoT62 because I didnt really know anyone and going any higher would close a pretty decent and SAFE solo spot in JPF. If I had a guild or a better network of friends pounding to 60-62 might have made more sense due to the insane XP one can get in some of those PoP zones at those levels. Each persons situation is different.
What you decided to do really is up to you. There are many viable paths for early AA expenditures. Max Archery like I did is one route. Getting a broader more defensive/hp base is another... live rangers do more DPS than dead ones. I would always do Run3 and Regen3 for general... they give the best utility. A mistake many Rangers make that plan on advancing to higher parts of the game raiding ect is spending points early on Stats. Gear will change A LOT as you move up in levels, and thus so will your stats. What you are deficient in NOW may not be what you are deficient in a month from now or a year from now. Dont worry about stats .... let GEAR determine your stats. Time put into AAs is hard enough to come by... put in things that will help DPS or help your survivability/utilty. Many kick themselves for spending valuable points/time on training STATS. Resist the urge.
Archery... CF3, EQ, AM1-3, Innate Camo, Fury of the Ages 1-3, Planer Power will get you the best Archery damage the quickest. It is aviable approach that gets you doing good DPS quickly to enhance group desireability so you can level or work AA in better places more often.
Survivability.... Natural Durability, Combat Agility, Lightning Reflexes, Combat Stability, Physical Inhancement, Innate Defense. These types of AAs allow a Ranger to do thier multiple jobs that much better be it CC Snare root and park activities to peeling mobs off caster to off tanking to just taking a hit if the mob gets flipped onto melee or you pull agro. A goodly portion of a Rangers defensive ability does come from gear, but defensive AAs can save your bacon especially Combat Agility and Lightning Reflexes... those two maxed are amazing.
Melee DPS Ferocity, Fury of the Ages, CF3, Ambidexterity, Veterns Wrath, Sinister Strikes, Relentless Assult, Weapon Afinity, Lightning Strikes etc... these AAs increase Melee Damage. With the proloferation of almost 1:1 ratio weapons going melee and skipping Archery certainly has some Viability. I wouldnt recommend this since the AA expenditures are HUGE to max melee damage whereas getting almost max archery damage with a PoP type bow is relatively cheap.
There are 2 good basic guides for AAs through PoP AAs that can give you somethings to think about. I dont agree with his more broad get a little of this little of that approach, but it is a heavily followed one and certainly Viable.
For AAs up through Class
