Ja Leute, ihr lest richtig. Ein Patch kommt.
Orginal is das von http://forums.relicnews.com/showthread.php?t=40553

Hey guys,

I thought Id make a quick post to address a couple of things people are talking about specifically with regards to the Eldar. These are issues that have raised their ugly heads post release, and we are currently working on fixing them. These will all be addressed and fixed in the next patch.

Seer Council
Yes, they are unbalanced. The main issue is not with their strength, its with their accessibility. We will be looking at solutions for them, and already have a couple in mind.

Plasma Grenades
These have a bug in them currently that cause them to fire off 3 times as opposed to 1, making them 3 times more powerful. Its an unfortunate bug. Again, will be fixed for the patch.

Conceal stacking
Again, a bug. If you have performed the Conceal research, the larger the Seer Council, the more you benefit from the ability (http://forums.relicnews.com/showthread.php?t=40543).
Zum Conceal gibts gleich auch noch was dazu:
we used 5 land speeders attacking a seer council and timed how quickly they died.

without conceal:
5 seers: 10s
10 seers: 19s
15 seers: 28s

with conceal:
5 seers: 31s
10 seers: 116s
15 seers: 195s
