The combos you list in the guide are all really bizarre, you never attempt to stun people because it's sort of hard to use your Q?

Only one of them even mention Q, and even then it's a bad combo. You say start with W (meaning it won't do extra dmg) and then use Q later, so you stun them.. then use E for free damage? That's so weird. E Q W is the best pre-6 combo because you can easily land a stun if you were in range to use E and then your W is impossible to miss because the enemy is stunned and it'll also do extra dmg.

For the damage combos - I find way better and more reliable to start with Conflagration and then Sear. E + Q + W = great damage.

I generally find starting with your ult is more effective, it spread your passive very effectively and i find the bonus effect from the passive not that usefull for 2 reasons 1 you re going to build rylai and 2 your ult will focus on getting 3 proc on a single target so the slow you will get it anyway.

my favorite combo is REW of RWE depending on the situation it mean you can keep your q for that pesqui divertor assasin who managed to get passed the front line.
