It's rather to hit optimal FCR breakpoints (99 for Java and 102 for Sin) and having both ring slots available for that.
yeah probably the most sensitive to do. But afaik that requires teleporting on weapon swap - a thing I am not a huge fan of. Diablo 2 is clunky as it is not having to do such things. Also, I think those builds are fun and good as they areIt's rather to hit optimal FCR breakpoints (99 for Java and 102 for Sin) and having both ring slots available for that.
Never a big fan of a pair Warshrikes on a throw barb. My first one used Dual Lacerators and on switch a Warshrike and a Gimmershred. Lacerator and Gimmershred are my preferred weapons. Gimmershreds with an Infinity Merc is awesome.
