elise smite

i rlly dont feel like elise needs chiling smite at al i buy it and sometimes finish a kil with it but its hardly ever really needed trailblazers is just the biggest mistake u can make her clearings r superior to most junglers she doesnt need mana or sustain i rlly dont see the point

what leaves bcus of her superior clearing i can easily counterjungle before my first back wich helps me predict the next enemy jg movement i havent ever builded this on her but i feel like in allot of games she would get the most out of this smite anny elise players got an opinion about this ?
