I Agree entirely.  I run a sentry with a tactical m700 with 169%headshots damaged ( elivated,prepared, brutal) with headshot mods in every available slot. my dps is 247k but I hit for 900k with 1.2m crit damage. (full disclosure  my firearms at 8100, total glass cannon and I play pve and I'll  get wrecked without my team) .
