Mala, malo, malosini stacking questions

[Daldaen]

Tashan line is unresistable and stacks with everything except other Tashan spells
Malo/Mala are the level 60 shaman/mage spells. They are unresistable but lower debuff.
Malosini is the highest Debuff available but can be resisted.

Ideal situation this occurs:

Tashan is cast and lands (cause unresistable) -39 MR
Malo is cast and lands (cause unresistable) -45 MR/FR/CR/PR
Malosini is now cast and hopefully lands and overwrites Malo (it should since the above two Debuffs combine for -84 MR)

Malosini is -60 Debuff whereas Malo is -45.

**If they ever fix bard stacking, a bard can proc a Tashan staff or Orb of Tishan and because bards were coded weirdly it stacks with other Tashan spells.
