I do not see this as a time sink as the stats are hardly noticeable. Someone made a post and you can get what an extra 30 will power which is...eh.
I would also say a new warzone is content and making WH the cost of BM is a huge improvement in the efforts to control the complaints on the forums.
heh. I kind of thought the same thing, if the ewh weapons are any indication. main stats are pretty meh. the only obvious advantage I found to ewh mainhands are that the hilts/barrels upgrade one's specialty power stat. exp, main stat and crit are all negligible. alac and power, however, could be serious upgrades (not that anyone stacks the former).
