Flame Wall intended to ignite?

Edit/ I can see that Cast on Ignite and Cast on Shock needs to be "On hit" Where Monk's "Elemental Invocation" doesn't, so it's actually very easy to fix, and it might even be a bug.

-Add "On Hit" tag to "Elemental Invocation" aswell, thank you.

I've recently seen a short on youtube of someone running around spamming Flame Wall triggering over 9000 ice comet - broken?

This combo is way too easy and feels disgusting, it makes every other build trying to go for meta gem feel redundant.

An easy fix would be to either give Flame Wall's ignite a cooldown, or make it a seperate burn effect.
Please GGG look into this :)

Many regards an otherwise happy poe 2 player!
Ps; i love the difficulty and the pace <3!

I have observed some more strange behaviours with Flame Wall + Cast on Ignite. I made a bug post here: https://www.pathofexile.com/forum/view-thread/3611414
