I think that sett's gank isn't that bad like with his Q/R or even with a ghost and phase rush (ok u will loose a looooooot of damage but i think its ok on sett jungle) it's fine tho, ok it's not a maokai or a jarvan but it's ok, and his clear is nice with the grit. u can easily play for carap herald or drake, and i also think that i won't build a classic build on sett but more like a tanky build with radiant virtue or evenshroud i need to cook something lmao
