Overview
The Essence of Celerity is a powerful, party wide consumable that gives awesome benefits, allowing players with difficulties with some content (Hard Mode etc) a little bit of room to move while giving the more experienced players more of a kick.

However, though a positive in some respects, it is also a negative.

At the moment it is part of a larger problem that is taking over the so-called 'Elite Areas' of the game, even aspects of Hard Mode like vanquishing. One of the more dominating extentions of this are the Perma-Sins. As many know the Essence is enabling Perma-Sins the ability to maintain Shadow Form with far greater ease: just with the correct investment in attributes with Deadly Paradox and Shadow Form itself. This gives Perma-Sins a far greater flexibility to perform speed clears, allowing for speed clears of elite areas in a fraction of the time that it seems was originally intended. A large part of the issue with the Essence is it's reduction of the player's skills recharge times. Currently, the effect is addictive, allowing it to stack with other reductions to recharge times, Deadly Paradox and the likes.

Suggestion
My suggestion is to have the effects of the Essence not be multiplicative, to stop them from stacking with other effects (such as how armor doesn't stack passed a certain level). Also, a reduction in it's duration - even to something like 15-20 minutes - wouldn't go amiss; 30 mins is an incredibly long time for such a powerful effect.

With this change in place it would still provide beneficial to the players who use them as some see as intended, while at the same time it might become part of the solution to the wildfire of 'speed clears' that are, for want of a better term, making a mockery of the 'elite areas' of the game.

Example
Using a Perma-Sin as an example: with reducing the multiplicative nature of the Essence a Perma-Sin could no longer, while under the effect of the Essence, maintain Shadow Form with just Deadly Paradox (20% + 33%, which is capped at a maximum of 50% reduction to recharge), the 33% reduction from Deadly Paradox would took over as the only reduction figure in the calculation, meaning that Shadow Form would only recharge 33% faster, not %50 faster which is required to maintain it.

(a general theme I'd suggest is for all consumables to not be addictive. ie: Don't allow Grail of Might's 100 additional health, 10 energy (etc) stack with a Candy Apple etc)  Consumables are a out-of-standard-mechanics effect, they shouldn't be allow to stack.
