An attempt to nerf Mosaic slightly while making poison more viable

Since its introduction Mosaic is heavily discussed in the community because of its sheer power.

Yeah the build is very very strong and can compete with the most powerful builds in the game.

This is a refreshing change in the long existing Meta and I love it.

But there is one little flaw with this build:

You dont need a lot to be super powerful, in fact you just need 2 Gul runes and 2 random bases to easily clear P8.

There is absolutely no problem in this build to be so powerful. OP is just the low gear requirement to achieve it.

So how to adjust it without breaking it? It makes no sense to nerd it to the ground because damn its so fun to play it.

Maybe we just need a little rework in the MA skill tree to both nerf Mosaic a bit and strengthen an underused element while maintaining the class lore of the Assassin.

And here comes my idea

POISON!

How about removing the most powerful MA charging skill Claws of Thunder and switch it to a poison charge skill like Blades of Poison.

The charges would work like this:

-Charge 1: Poison Damage over time

-Charge 2: applies open wounds and prevent monster heal

-Charge 3: AoE Poison cloud

This change will have the following effect:

Mosaic MA Sin is nerfed because the most powerful skill is switched with a DoT charge lowering the direct burst damage.

The poison element gets another use which is highly necessary. Currently only the Necro really uses it.

Assassin class lore as a rogue/thief like character using poisons is maintained and improved.

What are your thoughts about this?
