Here i go bringing up another old topic.
Ahh good ol t6. No way to get optimal, and only a few places to collect what we need to build the things we need.
I would suggest lowering the rediculous ammount needed to make bars, bricks and orbs. that 1600 to optimal is overkill. But yes maybe that is one of the points. We are not supposed to max, thats why many things that used to stack, like wiskey for example with other things are not allowed anymore.
But lets go to where we do need a boost and it is reasonable. Why not up all the gathering skills by 100 points or more, to allow us to gather the mats faster.
Or better yet. Place more nodes, they are to little to play with, especially whisps. if one more person is harvesting the same thing, there would not be enough for both. More nodes wont hurt and maybe some adamantium golems could help to collect more ore.
