The pierce swords are bugged. They inflict their damage prior to their attack, interrupting all attacks in their path. It is a bug that effects every single game of Lockdown. The damage leaders are always pierce sworders, who [pwn] all of LD with the bug.
HOT FIX THE BUG!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! patch needed asap
this is every bit as exploitable as looping arenas/floors which you have weighed in on as a bannable offense.
(Note: i don't think this should be bannable, it should be fixed)
Pffft pierce swords don't need a fix.... just need less latency.
