There is more to the MVP position then just kills and captures.

After a Battle, all the players in the Battle are given Medals based on how well they did in certain areas. The player that does the best gets a Gold Medal, second-best gets a Silver Medal, and third-best gets a Bronze Medal - regardless of which team the player is on. There's a set of Medals for each of these categories:

• Captures (the number of Control Points a player captured during a battle if in CPC)
• Kills (the number of enemy Mechs a player destroyed)
• Damage (the amount of damage a player dealt to enemy Mechs)
• Action time (the time a player spent fighting, healing, or capturing objectives)

Medals are shared if there's a tie. If 2 players get the most kills in a Match - 8, for example - they would both win a Gold Medal.

All the medals are tallied to determine the match MVP.

In short it is possible to get 0 kills but still get match MVP if you get enough medals in the other areas.

Okay thanks for clarifying what's up

Usually this topic comes up when someone get the most kills in a round but doesn't get mvp for kills or for the match.  There are certian weapons that act as score multipliers like mortars.  This allows a player to get less kills but get a higher score and thus place first in kills or for medals.
