Game balancing

If you're a COD veteran you will love the balancing gone into MW3. They changed the killstreak system into a point streak system. For example killing will obviously add to it, but capturing flags and planting bombs will also add to your point streak and with hardline pro you add to it every two assists. Also there are three types of classes to chose from. Not custom classes, but point streak classes. So assault, support and specialist. Assault obviously focuses on kills, so sentry gun, chopper gunner, etc... Support is focused on helping teammates so UAVs and their streaks don't reset when they die...etc and the Specialist who runs around with no support whatsoever and gets perks instead of streaks, once you're on an 8 kill streak you have all the perks.
