The problem with this fix is that it probably affects the most problematic units least. Vans and Helhirdings carry shields and are fast enough to cross the field in a round or two. Even without the glamor, it's hard to get enough arrow hits on them to matter.

EA Vanheim's Vanheres are unshielded infantry. Without shields they'll take more hits and they're slower so you'll get more rounds of fire, before they start slaughtering your meat shield.
Vanheres are good sacred troops, but I don't think EA Vanheim was considered anywhere near as overpowered as Helheim or the later Vanheims.

I haven't played with the Sidhe, but they're mostly shielded infantry right? So they'll get more volleys, but still take few hits.
I don't believe they're considered overpowered either.

The problem units are the ones least affected by the change.
