i think i read somewhere that Mob Enhance and Stealth Enhance are mixed in with the suit so they last longer.
i know that you have unlimited energy now, but what happend to stealth it seems to run down as fast as normal in c2 rather than what it was like when using Stealth Enhance.......

from the beta videos iv seen anyway

No beta videos yet, that was Alpha. And the game has probably been balanced since... You'll just have to wait and see. Stealth is ok anyways... It just can't really be used as a perma cloak anymore... Could be wrong tho
