The problem we have is simply the numerical values are too low:
- duration of the buffs are too short
- in most cases the actual values of the buffs are so low that even a potion or passive abilities of other classes are simply overwriting our active abilities that are the point of the whole class. You can imagine people are disappointed when a knight's passive aura provides better value for the whole party than what you can achieve with active buffing/spamming/sweating for a single target... I mean how hard it is to understand the problem with this...
