These are the bane of my existance on prodo. Unless I para/stun, wall in/poison field and dump... theres just no way in hell I'm going to win.4/6 chiv DP dexers have been around for awhile, just because Siege doesn't have them doesn't mean I don't fight them.
Esp. a 4/6 chiv archer with resist and healing with high stats. 4 second aids, instant cure/heal/apples/Remove curse... holy light spam... running shot. I have to stand still to cast and they just constantly move. I wonder if I can out DPS when they don't run away, but on the field... very few ever gave me the chance to try.
Dunno how you ever had success unless you had help or fought players who were just terribad... that template is easy-mode.
