The problem with MVP voting is that people usually look who has the most damage on their team or most healing and awards them the point, but I tend to be a close second in top damage and a close second in top healing.
For examplel an average end warzone screen can look like this:
Player A - 200,000 damage / 0 Protection / 20,000 healing
Me - 195,000 damage / 0 Protection / 180,000 healing
Player B - 20,000 damage / 0 Protection / 210,000 healing
0 MVP votes, while Player A gets four and Player B gets two.
There needs to be a new column for "Total Contribution Points" which combines all of your damage, protection, and healing. This will also, give the tanks some more love in the process as well.
