Jeez Nerf, don't go throwing around generalizations (like Zounce said). I know you're "back" again. Lemme get you caught up... I'm always trying to win people over to liking PKs... and this is a good tip for ANY HC player.
If you truly want to test a character out, you don't duel friends. At least I won't. Too many times accidents happen and charms get lost. Best way to test out a future HC killer is always to practice. When you duel/PK many many different types of builds you truly take the build to the next level. Dunno bout you but my friends tend to build the same character over and over and over with the same mistakes (not you Slick). Take them to their deaths and figure out exactly who they die to and there won't be any problems.
For example: What I have learned about this PK so far... Stay away from Hammerdins, Zealots, High Level MA Assassins, and High Level Fireballers. All other builds die super quick and with little problem. Given that Softcore has all of these builds and you see only 2 of them commonly in Hardcore, I would say I'm on to something very, very strong.
Once I die with her, I'll probably post the build here. That way everyone can enjoy in the fun and build one. And when you use the junk I've been using on Softcore (ie, see pic), by the time I build her in Hardcore she will be insanely overpowered. Can't tell me I'm not learning anything playing with an 8 box Lenymo my friend.
