Yes but what time is it in Thailand/Malaysia/Indonesia/Japan/Phillippines/Australia/etc when those away games are played over there? There are a lot of asian players in TE, possibly more than half the total players are asian. Take Japan for example, a 6am game for you is a 8pm game for the person in Japan, when you play at home at 12pm then its 2am to the Japanese player, It's not easy to cater for both players with a 14 hour difference, It would be worse if you were in LA on PST because the difference would then be 17 hours to someone in Japan, and 20 hours between PST and someone in New Zealand so its not always possible.
Plus all matches need to be completed by 8.30 pm EST because 9PM EST is daily mantainance in your part of the world.
