No, negative!
Othell is not the proper dual class for Tyrr Maestro.
You should bear in mind equipment (set, weapon) and dual skills to be proper for both - main and dual class.
Your mistake is very expensive, especially when you have to buy Dark/bloody sets & weapons for Tyrr & Othell.
If you are using Stormer (Pike) & Heavy Set, you should chose Tyrr Dreadnought, in order to use the same weapon and set for both.
If you are using Blunt (+hp) and shield, I will recommend you for dual - TANK.
I believe you catch what I mean...
So, choose carefully!
