So, as you can evidently see, the two main discussions in this forum thread are on the same thing.
Cybran are OP.
Whilst I understand the viewpoint. I would argue that the problem actually lies with every other faction.
I would argue that Cybran are not "OP" in of themselves, but rather that they are strong in every respect and so are the most diverse faction as they have all the right strengths in the majority of the right places.
So, rather than nerfing Cybran, why not buff everyone else... It solves the problem whilst also allowing for other factions to be played differently. Making the game more fun.
I had a discussion with Zock about this way back. I don't remember much of it but he basically won the discussion (as to be expected, I am not the most articulate or intelligent of people), but I still stand by this viewpoint.
Discuss!
