: 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.
: 所以还是只能带一个正式替补
: 此外，还有紧急替补规则
: 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.
: 如果先发五人中有两个外援，且正式替补又是外援，那队伍按规则必须要带一个非外援的
: 紧急替补（强制要带），怕你搞到最后变上三个韩国人打
: 其他应该都一样 紧急替补只有不可抗拒因素才能上场
按照L大摘录的英文规章，原文说第七人是为了避免有三个外援同时上场，必需有一个非外援的第七人，那不就刚好是GRX的情况吗？
先发无极+Raise，如果中路换替补Candy就会变成三外援同时上场，这时候就可以合理使用第七人(非外援)，原文并没有提到紧急或是紧急状况才能替补，只有说先发不能上场(unable to play)，如果说先发第一场被打爆、状况不好、心态崩了换替补应该也是可以的。(Olleh就有发生过，后来心态才回稳)
所以GRX就是带第六人Candy，第七人翻译，最佳解。
