Suggestion 3: Future-proof content by capping at least instanced fights and dungeons.

[Jinko]

Guess you could always give the option to cap versus not - then both types of players are satisfied.

True enough but lets be honest unless you are forced to do content with a cap the majority of time you aren't going to.

Having capped content leaves that in the developers hands, for example Ifrit easy mode, you just need to throw 1 level 50 at it and its less than 30 seconds. (where is the felling of accomplishment ?)

How are low level players supposed to learn group tactics if all they have to do is rely on a lvl 50 to one shot everything for them.
