Pro: Uncapped content will create a predecedent and it will be expected for future content that they are uncapped as well, alienating all depths in content, having devs design shallow/favor of the patch content. Allowing for only vertical progression like in WoW (making only new content relevant and desirable, even new players will just skip the old content) instead of horizontal character progression which makes new and old content relevant for new and old players.
Hmm. I thought I had that one covered already with
- If you uncap low level dungeons, high level players will simply rush through it; which basically means that you are wasting the lasting potential of a dungeon (which could be challenging forever with caps). Counterargument: None so far
Please accept that I have to be a little more concise, or nobody will read it ^^/
