經過大家的協助和網路上的資料，已找到如何使用英文介面了。
5.0.4版本realmlist.wtf檔已沒任何用處了，刪掉也不會造成影響。
這次改版暴風雪給大家更方便的設定了，只需要修改一個檔就行了。
(推測世界任何一版都適用只適用美版，
設定好後，系統會去抓相關的*.MPQ檔放到Data下面資料匣中)
第一步：修改Config.wtf檔
檔案位置：World of Warcraft\WTF\Config.wtf
(用記事本打開，確認下列參數)
相關參數：(預設不用改，只要確認)
SET locale "enUS"
SET installLocale "enUS"
新加參數：(在最後一行加入如下字串)
SET portal "tw"
第二步：新增字型檔(五個檔) --新增於 2012年8月30日 22:14
檔案位置：World of Warcraft\Fonts
原程式使用的字型無法顯示部份畫面的中文，所以必需更改字型。
在 World of Warcraft\ 下新增一資料夾「Fonts」。
到 C:\WINDOWS\Fonts 之下選擇你想要的字型，把字型複製到 World of Warcraft\Fonts 之下，並更名為
ARIALN.TTF再複製該字型四次，分別更名為
FRIENDS.TTF
FRIZQT__.TTF
MORPHEUS.TTFSKURRI.TTF
* 建議使用字型：Arial Unicode MS ( 檔名：ARIALUNI.TTF )、微軟正黑體 Bold ( 檔名：MSJHBD.TTF )
注意事項：--修改於 2012年8月31日 22:57
1．本文章只適用WoW美國下載的 5.0.4版本，請升級完成後再行修改設定。
2．驗證美版可行，智凡迪提供的版本不可行(網友測試過了)。
3．字型檔請留意副檔名的問題，系統預設副檔名是不顯示的(.ttf)
4．操作前記得備份。
