u cant play on ur setup anymore, u can use wires for info but if u want play around ur wires u cant, it just instantly gets destroyed u cant even have glimpse of enemy if ur trying to kill through cage
then ur probably using your trips wrong and im assuming "sometimes" means once a game or less.
u may get some trip kills like one a game or less as an added bonus or whatever but this still doesnt change the point of trips in pro play and higher elo which is about getting info rather then getting kills. you could be using your trips in the most perfect way possible and still get 0 kills, it's not the point of trips.
