That's less than half of a percent of the whole Imperium, in a century, that he can fix, even if everything is going smoothly and he is constantly traveling and winning his battles in short time, and that's not even mentioning planets that might get fucked up again somehow after he leaves. So in 100 years he might get to say, 3-4,000 planets AT BEST. In a year, not even accounting for traveling between planets, that means he can manage 50 of them, and that's if nothing goes wrong - no being sent off course during warp travel, no having to suddenly fight a war that takes a couple months (which is happening all the fucking time because he's a military commander leading a fucking Crusade of Space Marines first and foremost) etc. He has to meet with the right people, delegate, analyze, crunch numbers. How long do you think it realistically takes him to get one planets shit in order from a state of absolute fuck? At least a week minimum, even with all his skill and experience. Yeah Guilliman is great at managing things, but he's still one person. Half of them are completely cut off from the other half, and even at the best of times interstellar communication and travel is inconsistent, incompetent nepotist leaders are everywhere, tons of planets have regressed into medieval or stone age culture and tech level except for maybe a stronghold or two of civilized imperials living in luxury exploiting the primitives for slave labor, and everywhere is constantly under attack by Aeldari, Orks, Necrons, Tyranids, Genestealer Cults, Chaos, and some non-Chaos dissidents and traitors. The Imperium can't be fixed by one person. This has been discussed at length before. >otherwise he's just going to fix everything in the Imperium !idARBCCD!o34J9y-nNPSKFM-w4HxGWw!XdJBDSSR
