Not Really. Sophia normal doesn't teach you anything you need to know for extreme. even the tilt mechanic. in normal mode players just stand in the middle of the arean and completely ignore the tilts. you only slide across maybe 45% of the arena so if you're in the middle 10% you will never fall off. thus the tilts can be completely ignored.
zurvans another one. the soar in normal mode was nothing like the soar in extreme mode. and that's why so many players had problems with it and couldn't do that simple mechanic even though they'd cleared normal they had no clue at all how to deal with extreme..
which is basically everyone. the no bonus is to filter out players that haven't cleared content because the failure rate with those players in a party is incredibly high. that's why no one touched extreme primals in the duty finder because it was almost guaranteed to be a waste of time because of players with bonus...
the fact that everything already has an easy mode is why the player base is so fragmented and the no bonus culture exists.... if a normal mode fight was actually remotely difficult and similar to its extreme / savage mode counter part. then players would be a lot more willing to accept those bonus players into partys for those hard modes because the fact they cleared the normal modes would show they at least grasp the basics of the fight and have a minimum proficiency..
as it stands though the normal modes for most things are almost impossible to fail and teach players absolutely nothing.. even omega normal. the first one of those we 1 shot and didn't learn any of the mechanics at all. done that fight a dozen times and I still don't know some of the mechanics. but the reality is they can just be ignored anyway so not worth paying any attention to or trying to figure them out...
my earlier post was in response to someone saying a super easy mode would create a divide in the playerbase. and then cause problems when those players are mixed together. I simply said that already happens.. and it does.
when they added raid finder players complained that they couldn't get parties for extreme primals because everyone was using the duty complete option to filter out bonuses and thus excluding them and separating the player base... basically they wanted experienced players to carry them. and experienced players didn't want to waste there time with that stuff. which is why they added the raid finder in the first place.
the games difficulty already creates a massive split in the playerbase
