@Yuuki Tbh I'm not a big fan of the blue trinket on roles other than the adc.
A pink ward usually does a better job at giving you permanent (defensive) vision. And you need either a lens or the two additional wards (depending on how your team is doing). The orb simply has too much cooldown.
Also you gotta keep in mind that you'll probably never leave a ward for it's full 3 minutes
the area in which you need vision is constantly shifting
