STR build is the easiest build to play badly, AGI is the hardest build to play it correctly.
Therefore I call it "easymode". I'm not saying AGI is useless or anything, just that STR is much easier to be effective at, either for newbs or for skilled people. Simply because STR has way more advantages then AGI.
And as for extreme builds (over 27/12 or 12/27) it's just like you said - AGI extreme 9/30 or even lower STR cannot even be called a build, whereas STR extreme 30/9 and higher STR are quite effective (yes they have their counters, like the mauler, but still).
