Well these abilities can be used in a PvP setting while either leveling or outlaws den, anywhere where PvP can happen other than Illum or WZs you will be able to use these abilities.
That's the risk you take, buddy! It's pretty much the Wild West out there anyway, but it's not like they can spam them in PVP is it? 20 minute cooldown? If a PVP fight lasts 20 minutes, then both parties are AFK.
Stop worrying so much! 3 seconds of force choke on a smuggler every 20 minutes is SO not a big deal.
Edit: I goofed with "20 seconds" lol. Fixed.
