STR after 60...?

[zigzo]

Okay, I know the generally accepted build is 25 SPR/rest STR but I made my archer full STR basically because... I wanted to. I still crit constantly anyway, so I don't think it would make that big of a difference...

A couple days ago I read something on the Outspark forums (I think) about how a pure STR archer would have less effect from their STR after level 60ish. I can't remember where I read it now, though... However, I like my pure STR build. I'm stronger than a lot of archers who are a higher level than me (not saying like 20 levels higher, but at least like late 5x archers) even though I don't really use SC stuff. But I'm only level 51 at the moment. Should I expect to see a sharp decrease in the damage I can do for my level soon, around level 60? Enough that I should start adding in 25 SPR?

Thanks for any advice.
