if u dont mind downloading, u can download the client. then get a 10day free pass and try first before committing. see if u like it. and my suggestion is dont buy wrath of lich king first since u wont need its features until ur at least level 55.

u dont even need burning crusade if u dont wan to take the extra 2 races (draenei n b/elf) or the 2 professions. wait till ur level 58 then get it, maybe the price will drop even more.

and I strongly suggest against getting an acc from others as it is illegal + expensive + insecure + u miss alot of the content. whats worse is without experience in ur own character (thru levelling urself), at 80 u will be laughing stock everywhere, in raids, in Bbattlegrounds, in dungeons. etc

totally on this idea too, wireless broadband upload is one word: pathetic, and their pingtime to even local servers like lowyat.net is 300+ms, so even if u get no packet loss (which is almost impossible with wireless bb) and use a VPN, it'd be 300+ms (your wireless to local vpn) + 300+ms(your vpn to wow) adding up to 700+, which already breach most ppl's tolerance on lag (mine is about 450-500 cap)
