Online 1v1 Tier List
This is a tier list based on if you could play online PvP (or a 3v3 like MvC2 but you will get a DMG loss if you combined something like 3 Void Hunters)
I'm just gonna list some reasons for some characters in those tiers.
This is tier without their Additional Ability and they can still Evasive/Defensive Assist in to themself.
Most Supports and other off-field agents are too weak and their defensive moves are not good enough.
Hugo is only good in stun windows.
Soukaku is more high risk high reward version of Anby.
Ben is rated a bit higher than others because his kit is A-rank Armorer.
Roxy best move and DMG output is her EX which is good because it can pull in players into the tornado but I think their are many ways to avoid it.
Claret move set is good but her defensive moves are basic and her EX start up is a bit slow.
Seed and Jane dodges/counters are pretty great.
Pyrois, 2000 decibel Ult. Plus EX parries.
YSG is a tier below Soldier 11 because she needs build her resources for her Enlightened state but the from can be parried.
Soldier 11, hold basic *parry parry parry parry parry parry parry*
Phoenix can parry with her EX and come back to life.
Sigrid and Miyabi are more neck to neck, Miyabi has the speed, anomaly DMG, and her hold basic shoots projectiles. And Sigrid has the raw Crit DMG and daze output, can easily loop are basics, and she can hold basic parry into her attacks.
Yixuan I don't how but she turns out to be a to be the perfect fighter, she can parry with her EX, hold basic can ignore DMG as long as you want plus you can Evasive Assist with her perfected hold basic, and hold dodge does wide field DMG.
--Beta characters are more on section zone--
Kafka beta of her is not out yet so... more on the unknown for now.
Robin should be around a tier above Astra because she can survive longer and EX DMG should be a tier above Astra (who knows, she can released and her DMG output to Norma/Dialyn tier)
Sunbringer for now is a tier below Yixuan because her has perfect block EX and Evasive Assist perfect dodge hold basic.
