I’d say if you’re going ranger, it’s only either c1 or commit fully to it to c3. c2 is just that bad. Also, if you can’t get arde around 70-120, might as well go full bow when you hit 120. There are plenty of flying mobs around that range and even passed 130. A good level 120 bow investment will last you up to 170+ or until you manage to get mana-mana or karacha dagger + a decent crossbow. I went for a Tilly Bow at 120 which I enhanced to +6, socketed it with 2 lv5 green gems and still planning to enhance it to keep it relevant till I get the 170 replacements.
I reckon it will probably later than 170 since good weapons around those levels have steep prices.
