WW Barb IAS for 4 frame attack

This used to be so easy. Back in the old days 38ias on a CB gave you 4 frames. For the love of all things holy can someone please explain how you can get back to 4 frames??

I used a player planner and with 60ias on BOTD and 20IAS on Highlords it’s still showing 5 frames. So I socketed a 15IAS jewel in the helm and still 5 frames :man_facepalming:t3:

I remember others making similar complaints…i also remember reading it’s like near impossible now, because of the changes Blizzard made to IAS when D2R first released (or was after season 1? i forget, honestly).

Basically everyone kinda got, well for lack of better words, screwed.
