Leves when properly implemented will be better than simple monster party grinding by a mile. That is the last thing they should do. Grouping needs to happen, but not in an environment that doesn't take into account that the genre has evolved since 2002.
Well I did say I would want my ideas implemented after more PvE content. If they did the stuff I said hopefully we would large scale battles and content similar to Dynamis by then. If we had a bunch of stuff that people can do in a party other than grinding then people would be less likely to do it.
