IIRC 3x faster put the resource spawns at around 2 - 4 hours per node in the max level test ( still pretty extreme given how sparse heavy resources can be compared to requirements for building ). As for the refining, if you have more details on the actual adjustments to this and the new times ( the last test was a max level test after all, so not much testing was done on that side).
Between how rapid durability loss is (especially since it can't be repaired), and gear lost to PVP, it's imperative that the acquisition time of gear isn't painful. Too borrow a term used by a dev team that failed to achieve this miserably, it's important to get a balance of "easy come - easy go"
Ultimately player numbers ( and likely steam reviews) will speak for themselves if the right balance isn't struck correctly in a PVP game.
