When playing in some of these massive team battles, would you say kills or kills to deaths ratio is better....my friends would say i sucked because i had a few less kills than them but yet they had quite a bit more deaths and i never died more than i killed. If that doesnt make sense let me know too.

in any shooter game, i always consider best in terms of kills:death ratio not total kills

definitely. it takes more skill staying alive and having less deaths overall, then it does killing and dying a alot.
