I have lvl 16x Merc and a lvl 7x DB.
Both have similar gameplay, chaining a variety of skills to perform several attacks and have great mobility.
The downside is they both have low hp, but i wont care much about this.
Maybe i was amazed by DB's great avoidability, or even his OP hyper skills released recently in KMS, Asura is like the best skill among all the hypers, not to mention that the +1 attack to all the skills (hidden blade), i it so much lol.
However, Merc's passive 40% avoid rate is not that bad too, but her hyper is similar with other jobs.
It is kind of hard for me to make decision between two of them.
Also, if DB is suggested, will Phantom ever outshine him in any aspect?
