I noticed a few of you guys are building rangers. In my opinion, the ranger class is the most versitile class in the game. They can function as spikers (large damage in short amounts of time), AoE damage dealers (area of effect, i.e. Barrage), trappers, shutdown (energy denial and interrupters), solo farmers, etc. It is very easy to transition from one build to another with a ranger with minimal change in equipment or armor.

For any type of character, you should research builds and what secondaries go well with primaries before picking one. Later in the game it will cost you when you have to switch and play catch up with obtaining the skills. Most rangers use monk secondaries, because most ranger builds require monk skills. Mesmer is alother popular secondary for a ranger, but is more popular in pvp gameplay.
Armor
In my opinion, the Druid's class is best. Other armor classes will have an advantage in certain places, but have disadvantages in others. Druid's is an overall good pick for the energy boost, which you will need in farming and trapping builds. At 70 armor rating, and +30 vs elemental damage, ranger armor is tough. However the ranger shouldn't be used to tank enemies except in certain farming builds.

Bow choice is determined by build choice. Most of the time, you'll be using a longbow or flatbow. These have the greatest range. Pullers should always use one. While a flatbow has a slightly higher refire rate, its arrows have a slower velocity and fly in a higher arc making them less accurate. Hornbows are typically found in spike builds, due to their undocumented 10% armor penetration, which is stacking. Recure bows are also found in spike builds as well as needler and quick shot builds. Shortbows are almost exclusively found in farming builds. Of course you'll want a max bow, which is 28. My prefered stats for a general purpose bow are +30hp and 20/20 (armor penetration +20%, 20% chance). Many farming builds use a vampiric stat in place of the 20/20 stat.
