Well, I'm grateful for the efforts of the Mac dev's who are trying to improve the client. and I'd be willing to test anything they throw at me. Unfortunately, due to the low performance of the External GPU(Which I had to run a script to use with an older Mac and TB2 now, thanks Apple), and the RX580 attached to my 2012 MacBook Pro, I'm thinking about returning the GPU and just building a tiny Desktop with a Full Sized 1080 in it. I just won't want to buy a whole computer just for Gw2...but I will.
