WOW, athletics is one of the most important skills, none of the "good" players have less than 6.
Athletics is just as important as weapon master.
Which is to say that
it's not important at all, nor is it critical to a character's survival in any given round. Unless you're hybridizing your weapon proficiencies there is no reason to take
any weapon master, you can do perfectly fine with zero. I have 2 points in it, but my build would probably have been better off (and more versatile) with zero. The benefits you get from either a small number of skill points or stacking it as high as it goes are awful and have some of the worst returns considering the investment you're making.
As for athletics, you literally don't need any as well. Several good players have less than 6, surely, and several I know personally, whether they be on alts or not, have gone as low as 3 or under and have done just fine, if not more impressively than they would have with a higher agility build.
I occasionally see high athletics characters in NA and I caught myself thinking "ah, what a fun gimmick character those are...".
I have 9 athletics, and I consider my character to be hardly gimmicky. Of course, my high amount of conversions means that I also have enough strength for 6 power strike, so I'm not whiffing left and right, either; it's a very viable build. I definitely do get frustrated at the limitations that I encounter from lacking ironflesh, specifically, and the lack of my ability to wear armor while receiving the full effect of my chosen build. There is a huge contrast in the way that strength builds and agility builds work: The strength builds survive a ton of hits, and gain even more of a benefit from wearing armor, while agility builds tend to be much more frail and lose nearly every benefit of their spec from trying to circumvent that problem by wearing armor.
I just don't always feel that the investment in higher agility is worth it, as a non hybrid. So I run faster, big deal, it's not always impressive, and it's impeded by so many anomalies in map terrain and limited so much by the equipment you wear. Compare that to a high strength build, which would allow you make kills on people in however many less swings (which can not be overstated) and survive many more yourself, synergizing especially well with thicker armor.
Basically it's a comparison of
KILLING FASTER AND NOT DYING AS MUCH to
BEING ABLE TO RUN FROM MELEE PLAYERS AND CLOSE GAPS FASTER.
Agility, and athletics especially, are sometimes vastly overrated. That said, I wouldn't enjoy the game as much with less than my main has, it is so terribly fun to be able to run around at such speeds.
