Sooo where to put my stats? How much Dex to take? Rec or no Rec? Str but how much? Luc or don't be so silly? Wis? Ele tops or Forbid, or perhaps Stat only tops? Assault or Flash? Debuffs? Do I really need full  armour? Bows or should I carry a Jav/Xbow as well? etc...
It really depends of your current budget, but if i check your 1-15 gear, i have posted the following advise with a thought that you have a large budget
Now, in canta, it's not hard to get 900 stat build with that budget. The problem is to gain access to 4+ slotted gear. You cna get it from tiers or another players.
About weapons, i should pick bows. The attack diff between jav and bow is not much while the speed loss is significant. having a good attacking speed is an important factor in PvP. Since the difference is low, i should go for bows. Try to get it with ele2 or ele1 lapis. If you want to go with ele, go only if you have at least 2 different elemental bows. Fill in with lvl6 assault lapis and other lapis of choice. ( it depends of your stats, but i should pick craft.).
Enchant it to high lvl as possible.
About lapissing, i should focus on STR/DEX/LUC. As said before, you can get 900 stats, so aim for 480 LUC to have a nice critical rate. Add 250 DEX and then rest in 170 STR. The only problem here are sins with a lot DEX, like 350+. You can hit them, but with a slightly some more misses.
You can scale with the LUC/DEX/STR too if you want, but i should stay at 450+ LUC and 250 DEX ( it's already minimum if you want to be good )
To survive, rely on your absorption and HP from OJ's. Since you're on distance, you can see other coming to use slow or stun or having a back up melee toon to assist you.
This should be enough to have a good archer. Only problems might be guardians and high DEX sins, but DoT's can help ya here
