i am playing this game mainly on ps 4 since launch. i noticed that the game took a change in character's design, and the way they are meant to be played, but it comes more and more as a great turn off.
1. shaman is way to overpowered. in comparison to other characters, his kit is insane. she can be very unpredictable to the point of unkillable. she needs big nerf
2. peacekeeper has been nerfed to the point of uselessness. in a dominion match in teamfights where is better to dish out damage, she is utterly useless. the bleeds stack up but very slow. she needs a damage buff.
3. kensei top unblockable is very strong, it needs a nerf.
4. warlord needs a full rework. at the moment, he alongside conqueror are the ones who promote this turtle style play the most, which can be a big turnoff.
5. orochi light spamming is another problem, his attacks are way to fast now. the rework is okayish but he needs a nerf.
6. shugoki should move a little bit faster and attack a little bit faster.
7. the way combos are designed makes the gameplay repetitive for some characters. everyone keeps trying to bait something just to pull of the same combo. its either lack of imagination from players or the way this rock paper scissors is designed obliges players to do the same thing over again,
8. shinobi needs a full rework too, the way he is designed to be played is very predictable.

these atm are my points of view regarding the balance, im sure there are more but they dont come in mind right now.

One more thing, regarding the game modes, skirmish.tribute and elimination need a twist, no one is playing them.
Regarding the reworks, they are not much compared to heroes who got released with grudge and glory . they obviously are better than the originals, because it adds something to the kit, but compared to gladiator, shaman or highlander they lack the depth.
Greetings to you all!
