So I sent the following email to their customer service:
As a long time customer, I find the new splash screen on the US Website with the following:
"We recommend the following browser. For the fastest, smoothest web browsing
experience, we recommend the following supported browsers,"
to be rather distasteful. How would you like it if I went into a hobby store carrying my GW figures and was told "for the most fun, most enjoyable war game play Warmachine, Star Wars, or Wargods?"
I say, instead of having your website pass the buck on poor performance, find website developers that will optimize your US website for one of the most popular web browsers in the US, Internet Explorer.
