Honestly. unless you want to do your training IC, I would do the following. f you want to learn bows, the best way is to get one and then join the CTF group. I hate to say that, but you WILL learn your bow in that group for sure, especially if you do hour after hour of fighting.
Any other trypes, get a weapon and fight. Swords and Daggers and other melee stuff is a bit harder to learn but you can try it in the CTF group as well. I would suggest getting a bit of IC in with your melee learning. Find a Warrior and ask them to train you. It might get you beat up, or get you a no, but sooner or later in your travels, you will find someone that will teach you.
I asked who the best bow was and people gave me their opinions. I looked at whose name showed up the most and then I messaged them. We hit it off like the US and Iraq, but I didn't give up and finally after some pestering, soem cursing and name calling, I got taught simply because I would not take no for an answer. I would not suggest this method but it worked for me. All that training paid off and my first character was no slouch with the bow in anyones eyes.
Thats my .02. Others will have different opinions for sure. You can learn the basics of the bow in about 7 minutes. The rest is practice. Same with Melee. 7 minutes to explain, the rest is practice.
