Only thing I can defend agains is actually his zone lol. Everything else hits me right in the face.
My biggest issues with him is that he is fake Vanguard. Compared to other Vanguards he has so many options at his disposal and dodge attack is pretty important advantage. He is so fluid with his moveset and Raider and Warden next to him look like caveman swinging their wooden sticks while dancing around the fire. Kensei has like 17 or 18 different moves compared to 6 or 7 for other two Vanguards. And while Warden or Raider are almost only 1 trick pony, Kensei is probably most unpredictable hero overall, not just in Vanguard class. The way they built him is more that of a Hybrid than Vanguard.
Compared directly to Warden, here is why I am pissed off at Kensei or devs for making him like that:
1. Mobility. He is definitely more mobile than Warden with his dodge attack, sudden change of direction and spinning top strikes. Which would be ok if he was Orochi but he is Kensei, Vanguard class. Strong dude, well armored for a Samurai and his weapon is actually usually heavier and harder to manipulate than longsword. Same as Warden who surprisingly ( or actually not) doesn't have dodge attack.
2. Weapon is another reason why I don't get his moveset. So he gets to have thrusting move with his odachi but Warden doesn't although longsword is more appropriate weapon for thrusting. On top of that, Kensei is the one who gets pommel strike and although not historically inacurate, it is still much more fitting move for Warden, considering his longsword.
Imo, he cheated out Warden of his moves plus he already has a lot of cool stuff. Can't say I like it.
