Roles of new Classes

[Narvad]

for me Juggernaut is like a armored command

Exactly. Seems a bit useless to me. More like "fun" character. To charge bots in open field etc.

Hoplite stabs behind SHCs incoming enemies as aid to the slashers

Looks like marauder with -damage but +shield to me. Can shield like infantry hero, but armor is still weak.
Also preety fun in open field.
Probably the closest example is the marauder with shield + snake spear from the point of gameplay. But i do remind that overhead stabs with 1h spear was a bit slow and has a weird animation.
8 athletics, also, so it's kind of worse at kiting and in the open field.

Seems like new spears can be used on the horseback. Marauder with warmongers isn't the most efficient pikeman on the cav anymore.
I'm actually have a good feelings about this class on cavalry mode. Long spear(with good damage), decent shield, decent shield skill to catch arrows is what was lacking marauder.

Repeater just spams

Eastern Repeater got nerfed damage(reload speed + ammo quantity), but received a lot of accuracy, almost as good as Ailadrodd before. Exactly what it was needed.
Ailadrodd now class locked to repeatermans. This is good. Kind of.
I guess there will be more repeatermans than chosen marksmans from now on.

and Sentry is the Sentinel for 2h (slasher + archer)

Thrust mode of Sentry 2handers might be fun and useful, especially behind the cades.
