After having used threaded specter for most of a trials reset after facing an entire team using it with double dodge, I think it's too versatile and effective in pvp. It's in effect mobile cover, radar bait, aim assist drag, land mine, and zurg rush. I was using it as a shoulder to snipe over which I thought was funny. Even one player using it is effective, but 6 specters from three players in trials catches aims assist blocks projectiles and pings so much as to almost not be worth engaging. Specifically a problem in small map zone capture like trials on Pacifica. Not sure anywhere else, probably less of a problem on large maps is a very effective counter to very aggressive play. Edit: fixed wording to more clearly indicate I meant trials
