Firestarter, and other on-ability procs

What if Firestarter bluffs could just stack.

Honestly this would work just as well.

Is it even a problem at level 70? Or 60?

Well the issue is that if you're casting Fire I over and over again, and you get a Firestarter proc, you may overwrite that proc with the next chained Fire I if you don't watch the hotbar to see the proc happen a split second before Fire I finishes casting. Overwriting a Firestarter proc is a pretty big dps loss.

If you're spamming fire 1 at level 70 you've got much bigger problems than 'I sometimes overwrite firestarter'.

There's 18 levels between getting Firestarter and getting Fire IV. I'm not spamming Fire I at level 70.

I know that Fire I is not cast more than once in a rotation cycle at post-60, but the issue is with the way procs are handled for abilities such as this, where the spell that causes the proc is chain-cast and requires the mage to watch their hotbar at the end of every cast to make sure they don't begin another Fire I before using Fire III.
