Post SAW only 3 heavies are better tanks than Alicia and 2 of them are blacks while the other is a plat who has virtually no offensive presence when his skill is down and has literally zero offensive presence when his skill is up. Gellius has his place against the most elite super bosses but against practically everything else SAW Alicia is actually the more practical unit. She's basically Maribel if Maribel didn't kind of suck at life.
