Flash and Ignite Strategy

Usually when i play a game i like to flash to the person and ignite him so i can get a better trade off with my champ and do more damage in the trade then he does to me. Then i go ham and cheese and kill him because he has less health than me so i can kill him i have used this many times and it works 9 out of the 10 times. Also this helps because if you are one of those people who forgot to ignite at the end of a fight you can just do it at the beginning and you already have enough damage at the beginning from the trade you dont need to flash or ignite and the end of your fight. But to do this you have to be a very advanced player like me.
