Im not sure what class I want to do it as I have 3 classes in mind but which one it´s hard to deicded so will let you guys/gals decide for me. Also depending on the class I will get that class a nice armor to boot.  But yeah which one do you think  I will have the most fun with?

Warrior (Durandal just make me look like a awesome knight)

Berserker (Rely love the Jungle beast armor)

Musa (Does not have any cool armor I think I mean why have Ninja a Samurai armor when  Musa is closer to one)

Pick a class you like. Don't spend money on the cash shop until you get the gameplay of awakening and succession down. If a class doesn't feel smooth to you, try the next one until you feel comfortable and have enough data to compare.

Historically, ninjas are fighters who use guerilla warfare and covert operations which requires compact weapons, hence shorter swords. Samurai and ninja still used the same weapons. The major difference is that samurai were more of the ruling class while ninja tend to be of the lower class. Armor isn't class based (which is an incredible lesson that BDO gives). 

It would be much easier to just play each class and test it out.  You may get a lot more out of that than listening to others suggest what is most OP.

Your personal experience with the class should let you know if it feels right for you.

Is the pace right for you?

The combos?

The mobility?

It's tough for anyone to answer that question for you.

Yeah but the problem is I tried all 3 classes and like them but have only 1 one slot left so I had to delte them when trying the next so now when I need to pick one I can´t decided on one and well im not fan of buying charters slots.  So I wanted to say hey pick  one for me becuse I can´t decided >.<

Still would feel nice if Musa had that samurai armors as well becuse I love it and I liked Musa more than Ninja. So I wanted that Samurai armor name my Musa after Sengoku general like Oda, or Date and be a little bit of a cosplay.
