I'm not asking for drastic changes to these characters at all, I'm asking for slight tweaks to certain mechanics that these characters have.
For example,
There's no reason for a starter Vanguard character, Kensei, to have the best dodges, cleave attacks, combos and light attacks in the game, so I simply ask for damage changes to any non-direct attacks (cleave damage) for Kensei and perhaps a better animation for his dodge (as it can be quite difficult to track who he is dodge attacking in a group/gank fight, however this also applies to all dodge attack animations).
Furthermore, a slight 2-4 damage nerf on his lights and a 3-5 damage nerf on his heavies will still allow him to be a top pick for new and veteran players but won't allow him to harass/punish people with his hyper-armour.
Speaking of, his hyper-armour, in my opinion, should be either removed from his/her side heavies as the top heavy exists as a entry to mix-ups. There's no reason for why Kensei needs hyper-armour as his dodge attacks already exist with superior dodge. I understand Kensei is meant to be one of the easiest characters to pick up with a plethora of combos and the like, however, he/she doesn't need to do everything and anything. Just slight tweaks not drastic overhauls like the many he/she has already received.
Gladiator is in a really ****ty spot right now in the current version of the game. Overall he's a great and fun character to pick up in order to poke some toes, however, at a first glance that's his/her only appeal. As an Assassin I believe Gladiator to be perhaps the worst (not-including Shiobi). For one, Gladiator cannot light attack after a bash, he/she is one of the only characters in the game that cannot do this. If Gladiator was to do this then he/she wouldn't be stagnated after a dodge bash or bash off of a parry, allowing him to properly punish his/her opponent.
Additionally, more combos intertwining Gladiator's lights and heavies, perhaps even into a bash similar to that of Centurion, would make Gladiator a far more versatile character in both 1v1 and group fight situations. I believe outside of changes to combos Gladiator is a fantastic character that deals enough damage however currently cannot stand his/her own.
