DRG Gear question

Forgive me if this has already been posted here but I am in quite a dilemma.

I'm wondering if I should get my relic +1 or my myth chest.

The difference is this:

1. If I get the relic +1, I gain 2 weapon physical damage, 4str, 5 vit, 4 accuracy and 3 crit rate

2. If I get Wyrm's Mail, I gain 9 str, 11 vit, 6 det and 24 crit rate while losing 19 skill speed

I have no idea how the 2 weapon damage would compare to the 9 str and 6 det ill gian from the myth chest in terms of damage output.


tl;dr
Relic +1 or Wyrm's Mail for DRGs?

Refer to this thread.

Relic +1 should be high priority. Biggest payoff.

From my understanding, weapon damage is by far the best investment.
