Playing with 2-H Axe dps Marauder

Playing with this skill tree ;
And i need some advice. Better 2-H Axes requires more dexterity. Should i spend passive skill tree points to gain some dex ? What will the best for 2-H Axe dps Marauder ?

If you use an axe you should use Sweep. Karui chopper is currently the best white base to use because Sweep doesn't take base attack speed into account. That type of axe requires only 43 dex, which you will probably get from gear. Here are some basic examples of what you can expect to have at higher levels. Also looking at your build, you need to invest points in defences. Going pure dps nodes is currently not an option for melee.
