It is a benefit but in PS2 there are almost NO 1v1 battles. You are part of a larger collective and while you might be at a disadvantage against a fully specced opposition there are plenty of ways for you to beat him. Approach from an unexpected direction, get the drop on them, pick on pre-damaged targets etc etc.
There are a wealth of ways to be very useful to your team AND rack up the kills even with the basic kit everyone has access to. Every good kill streak I have starts with positioning to take the enemy by surprise and get the elevation or angle advantage in the ensuing fire fight. That applies whether I'm on foot, in a tank or flying high.
You are completely ignoring the point, this isn't a discussion about tactics.
