Well, yet another pretty useless post, but finding things to post these days are becoming increasingly more difficult. The sole reason that i am looking forward to Wrath of the LK being released is so that maybe i can get some MMOWNED rep by finding something out! Anyway, simple way to level wep skill is to get a warlock, FORCE him to summon an infernal and then keep banishing it. Although it is immune to your damage, your weapon skill still increases each time you hit it ( or the sheild its in). I know this isn't the most interesting of posts, but it was an efficient and easy way to level up weapon skill .
If this is a repost, feel free to use this post to practice your flaming.
