First of all you don't need to apply the statuses in one turn, that's ridiculous. Secondly, you don't need to be in range wiht some of the skills. (Red rain, haunting, again. Sanguine star. Other things too, probably. Like crystal rose. ) Third, you can spam it. And "just pops a throatopener" It's still a knockdown. Dense thunder is being used and it's litteraly the same result in the end.
And no, CM sear doesn't take half your HP if you're prepared. Will may be common, but even more common is res and resistances. No. "Bwah evokr nook me to death" is hardly a relevant issue nowadays. Refer to past threads involving magic to see how many counters and how easy to obtain they are.
If irremovable silence is REALLY the only way, double the duration of unmarkable should be applied, to prevent spam. Because as said, IRREMOVABLE Silence you CANNOT avoid is instant kill to full mages. And that's like what, six different class combinations?
