I recommend joining a dueling clan or finding a group of people who regularly duel. Unfortunately, private dueling is almost completely gone, and crap pub dueling rules the realms. Pubs might be a good way, but you will hear alot of retarded smack talk, and a lot of dumb hacks (TMC, TPPK, Flash Hack etc...), which will really take the fun out of it. I recommend to just leave at that point, and find another dueling game. Find people on these forums who duel, and ask for tips, duel friends, friends of friends, friends of friends of friends, join a dueling tourney, a ladder, anything. The best way is to just duel, you can only be told so much, you just have to go out there and get raped, and eventually, you'll rape back.
