I don't usually post on the forums, but this change has created two sides in this debate have clearly been drawn, and I'll break it down where SE really messed up and catered to a louder group of elder players and mentors who kept complaining about it over the years, until they finally caved in and all but destroyed any reason to keep doing these dungeons. When these changes was first announced, I knew without any shadow of doubt that SE would use this opportunity to nerf the exp and they did.
Castrum wasn't that bad at all, the real issues was the boss fights became a joke as expansions rolled out, ilevels increased and the difficulty became a moot point. Outside of weak bosses, the entire instance really wasn't that bad.
Praetorian suffered the most in this patch and ultimately SE has entirely destroyed it, because EVERYONE knows this is run for exp most notably to level sub jobs to make the grind more bearable because outside of daily roulette's is a slog and these once a day made it tolerable.
Praetorians only huge failure was the lack of being able to skip the excessive cut scenes, and YOU still can't skip them which makes the current dungeon basically two boring boss fights with slightly more complexity and 9/10ths less exp than you would normally get, this is an issue for players who are still levelling and for players who are levelling sub jobs, this essentially takes away a big chunk of exp earned each day, and that change is entirely unwarranted and as such, I am personally thinking about cancelling my subscription because of it until a new expansion comes out, because right now I'm using levelling sub jobs and this change just makes that longer and more protracted than ever.
In a nutshell, SE essentially saw this as an opportunity to massively nerf the exp from one of the best sources in the game. Was 45 minutes of socializing whilst watching excessive cut scenes as you wait to fight several bosses that at least provided some entertainment for the exp you earned, was it really worth risking all that for just updating the fight for a better complexity? Is it really worth to keep paying a subscription fee to keep grinding for longer periods now to make up for the daily experience lost by this change?
SE there were literally dozens of changes you could have done here that would have appeased both the vocal minority and players who continue to use these roulettes for valuable leveling, but you chose an option which literally nukes the entire instance into obscurity, for shame for shame.
