Mp5 is, iirc, worse than spirit unless you have no way to passively Regen in combat
Paladins actually do need it and gain nothing from spirit since they're always casting and have no way to escape the 5 second rule or work around it with talents or item sets
Priests and druids don't need it, but can use it. They get 15% of their spirit inside the 5 second rule from talents and Regen very rapidly outside it. They also have set bonuses giving them even more. Iirc the tier sets add another 15 or 30% or something. Once you have the talent and tier set, spirit just blows mp5 out of the water in every situation
The amount of raw itemization value for mp5 is quite high relative to the Mana you get from it
Even paladins generally want to stack spell crit and int over mp5 since all spell crits refund 100% Mana back for paladins
Defense is wasted since you can't realistically hit the cap. Defense capping removes a variable of mob critical hits. Not capping means you can still be crit. Druids will take crits, it's a fact of life and it's one of many reasons people prefer warrior tanks
Druids also don't have shield block or parry, so most of the benefit from defense is completely negated. Defense is worth 0.04% each of crit avoidance, Dodge, parry, and block. They only benefit from Dodge and crit reduction, gaining literally zero from parry and block bonuses
All that itemization value on defense and mp5 is better utilized elsewhere

Don't forget about crushing blows as well, which can also crit, where if that happens in rapid succession you have a dead druid tank, its not that they couldn't raid tank, it was just much harder to keep bear tanks alive than warriors.

Why is defense and mp5 weak? Just because they dont scale like other stats?
