How many of you have been able to collect all the parts needed for the SL Mechs?

The Atlas , Highlander, and Black Knight? And where are the parts at?

The SL Griffon is easy enough just by taking it during the Flashpoint.

I got 2 parts for the Highlander, but in all the travels I have not found anything for the others.

got a second HL and Griffin, Atlas have one part and saw one complete for sale on Blackmarcket, but was too expensive:Look for Star League worlds with black markets.

the hard one to get was the Black Knight and I started taking silly overpowered missions just to have more big mechs show up... cut the legs out from under him and bug out (fails the mission so don't do it to many times) before the 2nd wave rapes me

The Highlander with the AC slot (if that's the one you mean) I got by doing enough regular 4.5 - 5 star missions to finally complete the set. Definitely better than the P with the right mods.

I've only ever seen one kind of Black Knight. Is there another build I don't know about? The standard energy ones have been very common for me. Half the ones out there have probably been bought from me.

Atlases I have five of, but no Atlas 2 or even any parts of one. Pretty sure it's out there somewhere though as it's in the story campaign. Atlases being easy to headshot does kinda work both ways though. Avoid fighting uphill with them.

The problem I've got is I don't really know what I don't have. So many different builds to take into account. I know there are gaps in my collection, but I don't really know for sure in which class, much less which exact mech. It's only recently I've been able to get both Urbanmechs from a flashpoint.

I would love a UI overhaul that made salvaging new builds easier. Not just an indicator of how many parts you have; but also if you have a complete mech of that type too. Probably a few opportunities I've missed along the way.
