There was debate about the two rings in this thread
, and I have a couple posts explaining some of the factors near the bottom of the first page. There's slight imperfections in the math I posted (this was before we'd gotten solid confirmation about 2 acc == 1% hit rate), but those actually favor snipers a bit, so the conclusion remains the same.
At 60 you get +4 dex, +4 str. +4 dex is +2 acc, so we primarily just want to look at 4 str (Rajas) vs 3 acc (Sniper). 4 str is pretty much a guaranteed +1 fStr. At level 60 with TMH+2's and base +4 fStr, another +1 is a 2.2% increase in base damage; 2.1% if using CC's. 3 acc is 1.5% hit rate; if your base hit rate is 70% (moderately low) then the extra accuracy is a 2.1% improvement.
So, without even considering the Store TP or extra +attack from the Str, the Rajas is on par with a Sniper for total damage at level 60, and thus a "solid replacement" from that level onward.
