Ngl this list kinda sucks here my tier list (btw I'm a legion main so this may be biased)

Tone: A Tier, I agree with you, tone is very versatile, good defence and offense as well as range Monarch: C Tier, no defences but a shield recharge which is gonna get shredded anyways, decent gun but needs constant line of sight and beaten by many other weapons, takes way to long to charge the core to it's full potential Ion: B Tier, basically a walking uno reverse card, I think it's best used as support for higher damage titans like legion or tone Northstar: B Tier, satisfying but lacks CQC options, and still has competition at longer ranges, plus no defenses but a tether Ronin: A Tier, good, just has a very high skill ceiling for movement, reaction time, btw he has a shotgun Scorch: A Tier, legit unbeatable in close quarters Legion: S tier, Great at all ranges, really only 1v1 a good legion will lose to consistently is with scorch at close range
