[2022] have they heavily nerfed sienna dot damage on 4.6?

"Different Sienna DoTs now stackable as intended. Applying the same DoT now refreshes duration"

If I'm reading correctly, the same source of dot doesn't stack with itself anymore.

So it seems fire sword heavy 1 spam, beam staff and rapid m2 fireball are useless now?

In comparison, we are gonna see even more flail and shotgun staff, which was meta already.

If that is the case, bye build diversity I guess.

Lingerie flames seems the way to go now but I don't see as much reason to spam firesword. Battle wizard had the only use for the coolest weapon, and now I just don't see the point of it. Would famished flames be useful at all with the update?
