I main a DC, and except for a brief flirtation with a DO loadout, I have always used some sort of powershare AC build, and I love the feeling I get when people compliment me for what I bring to a dungeon run
That being said, when we all talk about buffs, all we are ever talking about is powershare and %damage increase, as that's all anybody wants from a DC or any other buffer, with the rare exception of also asking for Astral Shield
We do heal, and we do generally run at least one point in Cleanse (to strip DoTs) but we are primarily needed to run along with the party as a portable battery, and this is wholly due to the fact that when every other class out there can be built max out crit, armpen and lifesteal and as such all anybody needs from a DC is more power
Devs have tried to structure some encounters in the newer dungeons with damaging effects that they thought would require more healing from DCs, but unsurprisingly these effects don't matter that much when excessive powersharing (AC) and damage boosting (DO) trivializes those encounters
Yes, I said excessive
The problem is, as others have said, if it weren't for powershare, nobody would need a DC, so please, please, don't take it away! ...yet
For every action there is an equal and opposite reaction
For every twist or trick devs throw at us to make a new dungeon more complex to survive, there should be a counter, and the only counter we have available to us right now is brute force, and the effective brute force tactic we have is 2 DCs
We have the same kind of lineal thinking when we talk about debuffs... What we really mean by debuffs are still %damage increases for individuals or the party
Other Buffs that could counter negative effects in dungeons:
Increase the movement speed of the target to traverse an obstacle course to flip a switch
Increase the attack speed of a single target
Increase the health points of a single target over and above their normal max
Increase target's perception or range
Increase one of a target's physical attributes
Decrease the visibility of a target(s)
Conjure or call magical, divine or otherwise fantastic and powerful entities to aid the party in specific ways
Transform or Transmute someone or something into something else
Remove specific negative status effects
Other Buffs that could be beneficial to a party in dungeons:
Reduce the movement speed of the target
Reduce the attack speed of the target
Decrease the resistance of the target to various elements or forms of attack
Reduce the stats of the target
Cripple target's perception
Lower target's physical defense
Drain target's health capacity
Removing health over time while status effect is active
Remove or impair certain immunities and status effects such as shields
Mind Control, Confuse, Impair and for God's Sake: Turn. Freaking. Undead.
While that may seem like a lot, maybe there already exists a mechanism in a game bound to the limitations of the the buttons on a console controller... have you ever used a Wheel of Elements?
Class Specific, Multi-Effect Artifacts, powerful enough that to aquire one would certainly involve a fair amount of questing (note I DID NOT suggest grinding,) could be a game-changing addition to Neverwinter, as much so as introduing new levels or multi-classing... Moreso if several new class specific artifacts per class were introduced, providing more utility options
It's hard for me to see without my cool Cleric sunglasses, but I think this methodology would easily help Tricksters be Tricksters instead of just another DPS, and the possibilities for CWs and SWs could be endless... Rangers could have access to all sorts of Druidic hoo-ha, and Paladins could call upon whatever diety they serve for some really helpful stuff
Fighter classes.... Well, I dunno... I'm sure you could do something interesting... like maybe various martial styles and moves?
TL;DR: Powersharing is only a problem if the content makes it the only solution
