Good Solution To End Game Raid Issues
Problem: People who simply cannot meet fundamental skill challenges necessary to progressing in raids (aka, dodging, maintaining good dps, using cooldowns, and other acts of situational awareness) make it very difficult for raiders to form groups within the FFXIV community that can make progress. Socially uncomfortable screening processes to eliminate players can take weeks before a good static is finally formed.
Solution: A required single player encounter tuned to be as difficult in its mechanics as a raid boss that tests a player in all requisite skills. If he is capable of meeting end game requirements for situational awareness and his particular role, then he passes and can continue on to participate in the group content. Otherwise he just keeps dying, thus preventing him from becoming an obstacle to raiders.
