Enfin c'est Jayde qui
vous le dit 
Je laisse le soin aux apprentis nécromanciens de vous expliquer de quoi il en retourne ^^
As there are many threads and it seems that comments can easily be lost in the many threads.
AoE Damage Modifications
Parasitic Soul Swarm and Unholy Hands were dealing significantly more damage than similar spells and rebalanced to do the correct damage for AoE-based spells.
Similarly, the Archmagus pet was dealing roughly 25% higher base damage than intended and was lowered. This was a decrease of roughly 25% without feats, and 20% with feats. This is also in line with other AoE effects in the game.
Despoil the Soul
As was mentioned previously, the change made is an increase to the effectiveness of this spell compared to the previous mechanic. The decreases in damage mentioned above and from other sources are not due to this change, but due to other changes or issues. This mechanic will not change as it more accurately reflects the intended DPS increase of the feat when compared to DPS from each pet point.
However, we will be looking at the duration of Despoil the Soul in order to make it less of a burden to keep active.
Siphon Unlife Issues
We are aware of a code issue that is causing Siphon Unlife damage dealt to pets to scale with bonus magical damage. This is unintended and will be fixed soon.
Damage Coefficients
There was a data issue that has resulted in some spells, specifically Lifestrike and Flesh to Worms, not gaining the new damage bonus from +magical damage. This will be corrected in the next patch. (Lifestrike will gain 65% of your bonus magical damage instead of 11% as currently being used.)
Other Adjustments Coming
We will continue to review the damage to make sure that Necromancers are doing the target DPS at given levels. It is intended for Necromancers to be a competitive damage class at the top levels of DPS. Spells will continue to be adjusted until this the class is performing at the correct levels.
Additionally, melee pets will deal splash damage very much like normal melee attacks. This change will come in the one of the next couple code updates.
Edit: Future Updates
In addition to the pet splash damage and above mentioned fixes coming soon, the next data update should have the following Necromancer changes. Many of these were intended to be in today's patch, but did not make it in.
Necromancer
-The bonus gained from +magical damage has been increased on all damage over time spells
-Despoil the Soul duration has been substantially increased
-Despoil the Soul is no longer removed on death
-Frost Blast's area of effect has been changed to be a 90 degree cone in front of the caster
-Shatter now additionally works on targets affected by Frost Blast and Ice Shackle
-Dark Knowledge and Vile Insight will no longer appear as Hostile spells. (They will still persist after death.)
Mage General
-The bonus magical damage granted from Mystical Attunement has been doubled
This thread will be updated with additional comments if needed. Thank you.
