For all you Dark Knights out there

according to what fiel has told me back on sw forum

if you have 10k hp with lv15 archilles
and you get hit with 1/1, you have 750 hp remaining
so, thats 1500 hp with max archilles

when you have 30k hp, you'll have 4500 hp from 1/1

4.5k hp from 1/1, thats alot more helpful than 500 hp/4sec

Well, by the time you have 30k HP, you probably can easily have both. The question is which one to get first?.
-AlterWolfie, who thinks that you're under-estimating 500hp/4sec.
