Guild Wars 2

Ok, my son just started playing and I play on a Tier one server. Of course all of them are full so when he logged he had to chose a different server. I would like to have my son on the same server as me for Guild and WvW and I don’t mind paying the transfer fee since I bought the client on sale the fee is still cheaper than full price.

So my question is, are there any times (U.S. eastern) when the populations for BG/TC/JQ fall to very high or should I just plan on moving from my server that I have been on since launch? Also, (slim chance I’m sure) do you guys think I could get Anet to transfer him with a support ticket? Any help is appreciated!
