I like to play with Graves, Annie, Ashe
but Tristana is too much fun. Just because rocket jump is so versatile.
You can use it to flee enemies
You can use it to jump into trouble
You can use it to vault over walls
You can use it to feign running away, jump over the enemies, and then use buster shot to known the enemies back towards your own tower, trapping them there
The cooldown resets if you get a kill
Trist is soo much fun because of this one ability
