I've been playing a WW build a bit recently and wow is it frustrating in group PvE content. There is far too much downtime between combat what with quests, raid lead mechanics explanations, doing actual mechanics that don't involve dealing damage, and looting chests and heavy sacks that it's nigh-on impossible to stay transformed for the entire experience. I don't think it's unreasonable to ask for permanent WW transformation in certain activities, particularly as it could sit nicely alongside Oakensoul HA builds as another accessible option for players to do decent damage without the full complexity of a two-bar LA-weaving rotation.
(Incidentally, I'm aware of and use the "solution" - chug Ravage Health potions to stay transformed but that's frankly a ridiculous thing to have to do, and I would love to not have to micromanage that. Particularly in veteran content.)
