Yeah some traps are confusing and cells on movement and based slighty differently. (I could show you the Difference in the main traps I use just pm me)
Try practice on high orcs. Traps I mainly use are Ankle, Freeze, Shockwave, Skid, and sometimes but not alot Landmines.
Holy armor (lks), Ed/poison (sinx), Gr armor (bios,champs, sinxs mostly), OL armor water/wind (champs mostly, lk (element)), Fire tao/garm (Lks mostly due to there element), Marc wind (Wiz, people with freeze armor), Earth armor (lk element). Just the main ones I carry to pvp. (theres alot more)
Other useful gears are: Missy Mid (really don't need unless you hate carrying bgs, but I rather use di/wild mid) Wild Mid (crit build), Di Mid (Helps for more hp), and Esl Mid (Stone Curse users, big because classes often counter me with this status), Element Garments are very useful aswell.
I can also direct Snipers that I think are pretty awesome in pvp here to help. I'm sure they can help you far better then I ever could. lol
