I explained why it was changed in the update notes and I feel the explanation is more than reasonable.

Myrmidon
To prevent a single class having both a Physical and Magic type skill that cause Stun, the Stun from the 12s cooldown Magic skill Backdraft has been moved to the 24s cooldown Physical skill Dragon Force, and the Skill Paralysis from Dragon Force has been moved to the 24s cooldown Magic skill Phoenix Force. So the Myrmidon keeps it's 2 stuns but with a longer cooldown and both are now Physical type skills with Physical type debuffs so they can be countered more easily like the stuns from all other classes.

Myrmidon still has it's 2 stuns, although 1 with a longer cooldown now. Compared to other melee classes it's still absolutely fine. You still have other control skills of both Physical and Magic type that are more difficult to counter.

This update is similar to what happened with vanq a couple of years ago, this class will die

I personally don't think so, I think you are overreacting. The class has a lot of flexibility in it's playstyle compared to other melee classes and is still strong. It's just being changed to physical with a longer cooldown.

You do realize myrm still got 2 stuns, one is 16s CD other is 24s CD which is still pretty short, 16s CD for a stun
Comparing Myrmidon to wizard is a very dumb thing to do, Myrmidon can afford building a very high amount of HP while still dealing tons of damage
On the other hand, wizard cannot do that
Not to mention wonderland's necklace giving only 10% magic absorb putting all mages at a disadvantage by lowering their damage, and then they had their MP shield nerfed so hard that it can't be used now, myrmidon can heal 40% of it's HP, wizard can't, how on earth are you comparing these two classes?

Myrmidons magic damage is still pretty damn high, you are just always on HP set which makes you lose All attack stat which could've been gained from normal DPS gears, making your magic damage lower
And i have noticed that throughout all this time of you being a myrmidon, you never used the magic damage buff which is pretty much the source of magic damage for Myrmidon
You always choose 200 physical protection or the physical attack buff over it.

Didn't you yourself call Myrmidon an imbalanced class in one of the comment sections of your YouTube videos?

Monkey why are u bringing immobilizes into this without mentioning that myrmidon has 3 immobilizes itself

Wizard's also have selfbuffs like reflect and immu.
Almost every skill with additional damage and penetra, good compare.

After so many months keep winning just because no need to think on that class, YOLO spam every skill with low asf CD w/o any chance to avoid it (for example if u have problems with wiz u can buy magic debuff immu rune, there is also anniversary 50% sale which can help u with that!)
But after got killed by skill issue - REMOVE WIZARD STUNS :skull:
So strange when ppl jump between imbalanced classes and don't agree with fixes just because it's their main character.
And why u saying about other classes "imbalanced skills" only after that fix? Im sure we all know why.
Because who care about other classes when your is disbalanced asf.

What the hell are you talking about , have you forgotten сolo ? I have no problems against the wiz class, they are just like myrmidon according to your logic is an imba. Playing on the vanq/snip against the amoy/amadeus myrm, I did not feel that this class was "imba". There are strong/weak classes in the game. Sedy instead of killing a good class, make other classes strong (snip/ss/ww now dead class PvP), in many games there are testers , take 4-6 people to your team so that they would check you and clearly show what will happen to this or that class
