Auras in shadowlands are boring due to they are missing the original reason for being awesome.
Originally the fun part of auras was that they were a choice in strategy and it showed a large part on how good a paladin was where he or she did know when to use wich one to use like knowing when retribution aura would support the tanks aoe tanking and when the tank needs more survival thru either resistance auras or deviation auras.
And the same went for soloing.
What created this was the amount of auras and different situations that they were good in.
In shadowlands we got 3 auras
1 is for traveling that means we got 2 for combat.
These two are.
Devotion aura=flat damage reduction to everything.
Retribution aura=Gives a damage boost when people in the group die.
The problem with this is that you have 1 aura u will use 99% of the time and 1 that you will maybe switch to when people are dying.
This passive gameplay is alot more boring thereby i think it is a useless change to Shadowlands its almost better to not have it if it is this way.
