Which is exactly what they think they are doing by not capping it.
having things planned means nothing until you know a timetable. I've seen all the "dungeons" that people have POS hacked into and we all know about Ifrit. But if this content doesn't come out until after summer or is pushed back even further then the current dungeon gear becomes more valuable.
this is fundamentally different, I dont think people are saying that the dungeon should be on a once a week timer, or that they shouldnt make any content for midlevel players, they are saying that you should not diminish the value of midlevel content by making it something level 50s mostly steam roll. This content will be of very limited value for midlevel players, and EXTREMELY hard to do at the right difficulty, someone mentioned jumping on their level 33 glad, your level 33 glad is way more powerful than the level 25 anything. They cant add challenge to content in such a high range. something that is supposed to be challenging to level 30 is generally not nearly as challenging as to a level 33, also if any sp is awarded, you are gimping the level 25 who the instance was made for.
people dont stay level 30 for long, in about a week, from leves, they can be 35 or higher
What the hell. Is that saying we HAVE to have 8 in order to do the R50 dungeon. I'm sorry, but that is really messed up. With dwindling server populations, getting a group of 8 on at the same time can be a real chore. What a terrible terrible decision if true (and translated properly).
How about if the class rank is 10 ranks about the dungeon rank then the player get no loot and exp?
This is a key point. When level capped content in CoP was introduced, there were already capped BCNMs in the game... they knew how to keep characters under cap. There was also no possibility of changing jobs in the middle of the fight, so the cap only needed to be applied and calculated upon entering a capped zone. Applying a cap is a little more complicated in FFXIV since we can change classes freely ( and I'm guessing they don't want to disable this ability ) and the level cap would have to be checked every time we did this.
On the other hand, a one-time difficulty selection upon entering is very manageable, as it is already in the game for levequests.
My preferred approach though, is to include high-level passages and rooms. Just because the main content is geared for 25-30 doesn't mean there can't be deeper, more dangerous areas that provide a greater challenge and greater rewards.
