I'm not a fan of those TRO:SW or TRO:CI. They're inferior to the older TRO:3939 and TRO:3050.
Let's hope we get better TROs...
I wasn't thinking of those two.
Those are mixed compilations of older TROs, essentially stop-gap products for newer players.
I'm thinking brand new TROs, one styled after original 3025 with only Spheroid 'Mechs, one with only Clan 'Mechs, none of the compilations did this. Era is the biggest question, though era-agnosticism isn't entirely impossible. This would be the most logical split under current system, match the Kickstarter and how the box sets and force packs are currently sorted.
I would not expect these hypotheticals to be labeled with those compilation TRO's names, or cover the same time periods.
That said, given the fact we're marching toward unified tech-base, this split will not make sense in the long run. But it is thematically extremely appropriate, and i'm doubtful we'll be getting starter systems etc. moved to ilClan-era anytime soon regardless, keeping 3050-era relevant.
