As we can see in patch notes for Markarth release:
Buffs and Debuffs
All Major and Minor Buffs and Debuffs have been hard coded to go through server validation sooner and more effectively as cached values, rather than abilities that exist on your character. This new system will also properly ensure that no two same buffs or debuffs can ever stack in effectiveness, rather than needing to be individually spot checked on each application. It will also prioritize duration-based sources rather than permanent ones, so you do not need to fear losing their effects. While doing so, we have also properly reigned in the power of these effects into our Set Bonus Efficiency (SBE) standard; Minor effects are now worth 2 set bonuses (previously between .4 and 4.2) and Major effects are worth 4 (previously between 2.14 and 13.3). The new values can be found below.
Many ppl were shocked why you want to move even more calculations to the servers when they are in such bad condition (because of TOS I cannot properly describe them as it would be definietely be vulgar). Since the change buffs are often not working properly and other game issues like lags and crashes are even more tedious then before.
Are you sure this new system is not responsible for recent issues? [snip]
Can we get a honest answer what went wrong and more important, why did you push this patch in that state on live?
@ZOS_GinaBruno you promised us better communication (multiple times) so maybe an eso live with tech team or long and honest post? It would be nice if ZOS treat their customers like humans and not like walking bags of money. A little decency would be nice.
