I haven't actually played with the new factions as such, i've spawned in the new capitals as tech to see what they can do, same with titans, i also got the other races in game and used that to glance over their tech trees at the new stuff. but i've not played games as them. So i haven't actually tried the new stuff, such as the mobile capital.
I don't want to go into too many detals, but in short you need a enough labs to actually research a tech to get the benfits of it once researched in most cases, (not all do though). Your fleet cannot provide the full 8 of each. Likewise your income and ship replacent capability are simply not workable long term. If you can't kill your enemies rapidly, tottally ripping up your roots is not workable. Likewise there's a catch to devouring planets that hasn't been mentioned, (at least according to the research description), so it's not as simple as you'd think. Bassiclly your still going to have to defend a couple of worlds to make loyalists work. All the research lets you do is cut that number drasticlly.
Thank you for answer.
Are you talking here about the ability to devour only your own planets, not the enemy ones? Because that is known already, thanks to Yottsu. Or is there something else?
Anyway, i am not expecting it to be easy pie, playing the game completely planet-less. Actually i hope you would be able to have planets and at the same time the ability to use your titan as your capital, fleet beacon for ship construction and planet-devourer. Same thing with Capships working as labs/trade-ports, i hope this abilities are not exclusive only to situation, when you have no planets at all. The only advantage of going completely planetless would be that it will make you difficult to finish off, but otherwise i think this would be only last resort thing, not modus operandi for loyalists.
