Mentor roulette is broken and not what it seems to be ... the way Mentor roulette works is simple.

Mentor roulette goes backwards from the party that has waited the longest. It has nothing to do with sprouts or new players.
And because Ex trials dont fill, its why they pop up.

I now have about 2500 Mentor Roulette wins, and won all ex trials up to Sephirot, which is absolutely not possible imo.
Ramuh ex i won once! And this is where the problem of mindset happens.

Players: you don't df ex trials, everyone has a different progress point AND also a different mindset (go blind? Watch a guide?)
New player: Just queue, so far there was no challenge anyway.

If you queue for extreme let me give you a sample

Player 1: You
2: Has never done an ex trial
3: Does not read Chat
4: Does not basic grasp of his Job
5: For some reason in ilv 50 gear
6: Knows the fight but has not cleared
7: Queued for all languages and no communication is possible
8: Another Mentor

This is a sample of runs i had, there is just nothing to be done. I also keep reading stuff like "just queue in all languages so you get a faster pop for dungeons" and then i end up with 3 French ppl who i cant even tell what's happening.

If we can have a popup before Bozja and eureka, give us a pop up saying "your about to leave the handholding zone, this is endgame even if its lv 50 you either carry your weight or you will waste your own and everyone else's time"

If i see Ramuh or msq, i bail ... make a sandwhich, craft a bit and do something else. 30 Min Penalty does not mean i need to sit in front of the pc and feel bad.
Also, if you increase the punishment ... the reaction you think you get and the reality you will get wont match. You will scare of players, less will queue ... you wait longer and players will still toss.

Who cares if they had a 6h ban if they did their daily mentor roulette before going to bed/work.
