: 3.2 Roster Requirements
: Each team is required to maintain, at all times during the WCE, five players i
: n the starting lineup (“Starters”), one substitute player (“Reserve”), and
: a head coach (collectively, the “Active Roster”). If any of the Active Rost
: er is not present onsite,then the team is subject to penalties. Any penalty ma
: y be waived by WCE officials in situations deemed by WCE officials to be an em
: ergency.
: 所以還是只能帶一個正式替補
: 此外，還有緊急替補規則
: 3 Seventh Player Requirements
: A team is required to maintain a second substitute player (the “SeventhPlayer”) where (i) the team’s Starters are comprised of three Residentplayers and two Non-Resident players; and (ii) the team’s Reserve is a Non-Resident player. In this circumstance the team is required to maintain a Seventh Player that is a Resident player. This Seventh Player requirement is intended to protect against situations where a Resident player becomes unable to play at WCE and the team would be unable to field a
roster with its Non-Resident Reserve due to the prohibition of three Non-Resident players as Starters.
: 如果先發五人中有兩個外援，且正式替補又是外援，那隊伍按規則必須要帶一個非外援的
: 緊急替補（強制要帶），怕你搞到最後變上三個韓國人打
: 其他應該都一樣 緊急替補只有不可抗拒因素才能上場
按照L大摘錄的英文規章，原文說第七人是為了避免有三個外援同時上場，必需有一個非外援的第七人，那不就剛好是GRX的情況嗎？
先發無極+Raise，如果中路換替補Candy就會變成三外援同時上場，這時候就可以合理使用第七人(非外援)，原文並沒有提到緊急或是緊急狀況才能替補，只有說先發不能上場(unable to play)，如果說先發第一場被打爆、狀況不好、心態崩了換替補應該也是可以的。(Olleh就有發生過，後來心態才回穩)
所以GRX就是帶第六人Candy，第七人翻譯，最佳解。
