Dead Space Spitter not powerfull enough

Question 1

Just reached level 60 and my Spitter power is not power full enough.

In multi we are all level 60 and it takes me 7 spits to kill  a player..

If I get hit twice by a Spitter im dead???

Is there away of reapplying my unlocks? to make sure they work.

A few crashes on the way, may have caused this prob?..

Question 2 ,

 Noticed sum players with graffiti suits in DS2 multi , they where only level 2?

How do we get there suits, there a cool idea..

Question 3

 Will there be an editor so we make our own suit graffiti color?

Question 4

 Will there be a DLC for DS2 multi. New weapons from DS3 or new necro's.

Thanks Cheers.!!
