FYI, most ppl don't consider a 18 24 or 24 18 an agi or str build
36 - 3
9 - 30
Staying alive AND contributing to the team is harder as an agi build. Have to be good at it to get points/ kills.
A lucky strike of an agi build makes someones cheek itch, a lucky strike of a str build obliterates your face beyond recognition.
So yes an str build is easier for noobs, that doesn't mean there is no such thing as a pro str-build player.
