Well for now the class only has one circle but i’ve seen some videos and it wasn’t bad. Don’t forget that there will be higher tier classes, but i think with mounts maybe when the hackapell will be out it will be better so that your “start is usefull”. Thing about the Schwarz : you have a skill that can be used every 2sec something like that. That’s why you doesn’t really need the low level classes skills with it. It’s pretty sad if you can’t use any buff,
For Rank 2 take eitehr Quarrel Shooter or Ranger for scatter caltrops or Steady Aim.
Since hunter/sappers skills can’t be used while on the mount, either you take hunter skills so you can have your pet attack when you unmount, either you continue your rank 2class for second and maybe 3rd circle to have Scatter Caltrops or Steady Aim to level 15. (I would take the Quarrel Shooter if it was me i think)
I’ll finally take Wugushi for Rank 4 + 5th or only for Rank 5th since you can use every 1st circle skills of this class with your schwarz.
So if it was me i would go :
1/ Archer/Quarrel/Quarrel/Wugushi/Wugushi/Schwarz Reiter.
But you can choose:
2/ Archer/Quarrel/Quarrel/Quarrel/Wugushi/Schwarz Reiter
3/ Archer/Ranger/Ranger/Wugushi/Wugushi/Schwarz Reiter
4/ Archer/Ranger/Ranger/Ranger/Wugushi/Schwarz Reiter
You can even mix Ranger and Quarrel but like i said you have only one skill that can be used with them.
So i think eitehr 1/ or 3/ are the best choices since you can have two ranks of wugushi and pick 3-5skills depending on how many point you throw in them. ^^
By the way you can have a playstyle of mounting/unmounting + switching weapons to use skills of other classes, it would ask you some time to be efficient (learning your keys so you unmount/mount fast enough) The switching weapons isn’t that hard since you have 2 weapons slot which you can switch off like having Bow/Dagger in one slot and Pistol/Dagger in the second.
It’s you to see what you can do with your class if you want to play it that badly, there are always ways to make it good ^^
