No dude, you don't have to 'grind' out for WH... I DID have to grind out, for months, for my WH gear, what you have to do will take a couple days.
On that note, the only thing that was an upgrade for me on the EWH side was the MH/OH, then relics, then helm, then legs. Beyond that was either a downgrade, or +1 stat.
