Anything new for characters at the end game? 

With CoX introducing Incarnates does CO have any plans to expand the level cap or introduce new powers for those at cap?

I know CoX is much older but this game has been out for a few years (I think...two, right?)

Actually, when Vibora Bay was released they set the tier 4 powers which requires for people to be specialized towards one area, elemental, tech, might, mind, or mystic. However, they are still optional and some builds are better without them . 

I think they are named: Energy storm, implosion engine, fury of the dragon, mind link, unleashed rage and planar fracture. 

The game is one year and half old, hopefully after some more content Devs will start thinking in extra character development.

It is relatively young...I do hope they add more content at all level ranges when they do.  I also hope there is some more character development.  That is the hardest thing to do, particularly in this game cause raising the lvl cap really won't work because everyone will eventually have all the same powers.
