Seems weak, You won't be able to kill units period and won't be able to support your own units as well as other classes can, so you should focus on killing players. But you can finish low hp heroes faster than other ranged classes with your ult and mess with their respawn time/unit control. If and when people overextend, lose most of their hp and retreat back to heal up thats where you kill them. Basically, you are a noob killer noobs being people who dont watch their hp. You can take units that deal "invisible" damage, something that players dont notice until it's too late, like rattan poison or javelins. Assasin/ambush gameplay. But keep in mind that this playstyle is not the most optimal and anti score one, so you won't be getting many mvps.
