Death Knight aether damage build issues

Hi,
I wanted to build a board and plank death knight with aether damage. The idea seemed cool from roleplaying point of view, but I have big problems.

I expected a tankier experience, but when I face undead, the game slows to a crawl and when there is undead boss, it can be and unkillable obstacle.

I don’t want to abandon this build, but some tips on how to overcome this would be great.
I am level 30
My main damage skill is Blade Arc (12), damage 413-498 (222 aether, 229 bleeding)
Secondary is Ill Omen (5), damage damage 90 (41 cold, 49 vitality decay)
Plus Spectral Binding (14)

Thanks

Post up a grintools link to your build. Also, undead enemies heavily resist bleed damage.

likely means you don’t have much aether dmg yet/no conversion or skill mods

blade arc is not exactly great dmg on 1h, unless you have a ton of items to boost it
and if you’re then trying to do aether without conversion on top, well, then you just have a low dmg 1h attack with unscaled bleed on top
