as of 1.18 i concentrate solely as a Lancer DD, because is so much more worth to be a Supporting Debuffer/DD than being a multipart Cross Classes, again this is not everyone's way, some may be differ, but mostly basic skills will remain the same(Moonrise+TwistingVice combo).

Here is my Stats and since i concentrate more towards DD... (in bracket is overall +items)

Str : 160(185)
Vit : 85(91)
Dex : 85(92)
Int : 14(17)
Mnd : 17(17)
Pie : 15(15)

P/S I dont have 50 so i do not know how to assume a Phys.Lvl. 50 :P but this is done for Phys.Lvl.47 :3
