Whenever you use metabolism successively on a teammate there is a "imaginary" cooldown of about 30 seconds EVERY time I use it. The description of the ability does not show a cooldown of any sort and when you use the ability the button on the D-pad HUD does NOT gray out and slowly refill to show a cooldown. It simply does not let you use the ability on anyone for about 30 seconds or so. You can push the appropriate D-pad button for the ability and it will glow blue showing it is selected, but the interaction button does not appear on ANY teammates whether they have the buff or not. This happens regardless of if you have enough supply pips or not.
This glitch has happened since the launch of the game and is still happening to this day 8-22-11 with all patches and DLC.
I have the game on Xbox 360 and have the DOOM pre-order pack if that makes a difference.
I use the Metabolism buff frequently and would love if this glitch was fixed as soon as possible.
Thank You,
