I don’t know who makes your website but DAMN a random 14 year old could probably do a better job - there are dozens of basic JS errors in the console.
Reason for this post:
“Change Character” only works about 60% of the time for me - it just hangs on the super cool Blizzard loader. Console shows an http request error No data found for path/to/char/i/want/to/change/to
P.S.
Keep the loader designer, no complaints there
