Project: Gorgon is a 3D fantasy MMORPG (massively-multiplayer online role-playing game) that features an immersive experience that allows the player to forge their own path through exploration and discovery. We won't be guiding you through a world on rails, and as a result there are many hidden secrets awaiting discovery. Project: Gorgon also features an ambitious skill based leveling system that bucks the current trend of pre-determined classes, thus allowing the player to combine skills in order to create a truly unique playing experience.
The Project: Gorgon development team is led by industry veteran Eric Heimburg. Eric has over a decade of experience working as a Senior and Lead Engineer, Developer, Designer and Producer on successful games such as Asheron’s Call 1 and 2, Star Trek Online and other successful Massively Multiplayer Online Games.
The main example you are giving is 6 players with i'm guessing purple/yellow modded gear. My experience is mostly red-yellow gear with no transmutation/augmentation done in a solo environment, so of course it's quite different. I'm not fighting elites, just regular mobs.
Here i find i'm better off not equipping any epic attacks (unless i happen to have really good mods for one) and going for abilities with higher dps. If i can kill one mob with 4 moderate cd abilities, then one with another 4, then one with another 4 so that the first set is coming off cooldown (or something like that), i can work into a good rhythm of constant killing.
Cooldowns are the limiting factor in how fast i'm able to farm, rather than power (generally waiting for one or two ticks from food between mobs is enough). I haven't worked out the numbers, this is purely anecdotal/experiential.
