Especially after the chaos strike buff and with the chaos cleave talent, even first blood would b higher n priority due to the low fury cost and usually the ability to use 2x chaos strike and a blade dance within the momentum window, if specced for chaos cleave then you'll be able to atleast weave in 3 chaos strikes (which could refund depending on crit) all of this is a dps increase over eye beam at that point.
Most theorycrafters (including wordup) suggest you to use it on cooldown and preferably right before using momentum, tho fel rushing and using felblade immediately is also really good and will provide you garanteed fury for a chaos strike, optimally you'll want to get 2 in then. As previously mentioned in the tl;dr, don't keep it for momentum, use it on cooldown and if it isn't gonna fury cap you so you can gain momentum afterwards and spend all the fury.
