BM Armor Shell and WH Armoring

Hi Fellow Shadows,

1) I have a simple question for upgrading a PVP Battlemaster Survivor set. When getting War Hero pieces of a different armor set, if I place the WH armoring/mod/enhancement into the BM shell (for both looks and function, as I've been trying some DPS stats alongside the Survivor set stats and bonus), which set bonus applies?

I just would like to make sure the BM shell set bonus overrides the WH armoring, so I don't lose the 4 piece set bonus - 5% extra damage while guarding is pretty great.

2) Any advice for how to get ranked warzone comms the fastest? I am not part of a PVP guild and do not have the time to join one, really. Do most people simply solo queue PVP to get their WH sets? How long does it typically take to get all the armor pieces?

Thanks for your input!
