any other mechfags also think the liber is way too similar to 2e in that there are very obvious way-better-than-the-rest-by-a-country-mile units?
multi-melta thallax solve both dreadnoughts and vehicles since they're deep striking, mobile infantry that are cheap as hell and reasonably accurate
thanatars and lightning cannon + macrotek krios delete both normal infantry and elite infantry with breaching, large blasts and are also extremely durable
everything else are either bad melee units or kind of funny objective fodder or have worse firepower
