Tier List Ranking Criteria

Sub mobile suits grant their main mobile suit their stats, along with their sub-skills. Some sub-skills are much more useful than others, offering their main mobile suit powerful game-changing buffs, while the weakest ones don't really offer very impactful ones.

Our Sub Mobile Suit Tier List is ranked based on how potent certain buffs are, how often these are useful in battle, how versatile these are, and how useful the affected buffs or status effects are in the current meta.

Sub Mobile Suit Guide

Tier List Ranks Explained

	The best of the best. These mobile suits offer some of the best sets of sub-skills in the game, which give the main MS access to either very powerful statuses or impactful buffs that are easy to activate.
	A notch below the SS-tier Sub-MSs, but they are still very effective units. The sub-skills of these units may be slightly more niche or less potent than their SS-tier counterparts, but are still generally very effective.
	The mobile suits in this ranking have good sub-skills, but may be useful only in a small select group of mobile suits, or the activation conditions may not be easy to fulfill for the average unit. When used as sub-MSs on the right units, these may be just as, or even more impactful than, higher-tiered sub-skills of Sub MSs.
	The mobile suits in this ranking have sub-skills that are either very niche, or are not very good. They will still bring some value to the table, though the effects may be underwhelming. If they happen to be effective, it might rank low because it is too niche to rank any higher.
	The sub-skills of these units may be lackluster in terms of potency, or the affected stat may not be as useful to most units. These units might still provide some value in the right units and circumstances, but they certainly won't top the value of the higher-tiered units.
