I bought this Stealth Suit that offers the same sound suprression, while adding some Endurance, some item slots AND 2 armor mod slots. Yeah, that's not OP for a Stealth focused person. The invisiwalk is hilarious too. I started a mission where a guy was walking towards me, so I went into invisiwalk and just popped his throat from the front and casually strolled away.
You can tell Obsidian threw in the "commando" class at the last minute. This was clearly a stealth focused game. Very uneven and unbalanced game. All of the levels basically ask for stealth approach. The only time a commando would come into play are the RARE moments where the alarm goes off at the end of the mission and enemies start pouring out (Darcy's mission in Saudi, the Shaheed boss fight)
