While the delay saddens me primarily because now I'll have to juggle two games around the same time frame, I to however share the sentiment that I'd rather see EOD get the development time it needs if ultimately the end result is a quality experience.
I am also curious on the technical reasoning behind why they've chosen DX11 over 12, though given the age of DX9 at this point I'll take anything if there is a chance it will help with the long standing performance issues the game has endured over these years.
With DX11 on the way I'd like to hopefully see the addition down the road of an LOD draw distance slider option and maybe even some reworks to the post process effects and lighting, right now with post for example you can use 3rd party solutions such as GW2hook etc. but I'd like to see the need for these options become disincentivized unless for the purpose of fancy screenshot taking.
