Someone is either an idiot or a jerk.
Get as much WH as possible. EWH is really not that big of difference.
Totally agree. Your best choice is to fully max your comms then when you reach lvl 50 buy as much WH gear as you can. There isn't really not much improvement for the EWH, except of course for the looks.
I personally geared my Merc in full WH before buying him the EWH chest piece (he really looks bad***** in black!), but before turning in the shell I ripped the mods off to min/max another piece. Besides, is way easier to earn ranked comms at lvl 50 (PVP dailies and weekly) than when you're 10-49.
