my advice for you then is to not die as much so people can't teabag you for nearly half a minute. i also play ninja frequently in frontline and their role is like a glass cannon harrasser. apply dagger toss liberally, shukuchi to escape/close distance, and always make sure your teammates are in sight. it's easy to get tunnel vision so make sure you're paying attention. stick with your team, focus on low hp targets. jugulate casters and healers and follow up with ice ninjutsu for maximum silence time.
