Well this thread is about PL, not inviting higher skilled(weapon skills) DD's to kill faster. You can already do this in FFXI without level sync, yet the XP is ruined. For example, say you have a party in Qufim that a Lv75 WHM joined. Unless your group synced, you would get screwed on XP. However in FFXIV, you receive no penalty according to SE, so the uses of a PL aren't the same. Level sync will exist in FFXIV too, but it seems for missions and other stuff where you can cap your skills.
Um, inviting a higher leveled person to help a lower level person level-up much faster is PL'n, just inside the party instead of being outside curing. Now in FFXI this was not possible because the higher level person would kill the exp given after the kill. I suspect they will set some standards to make sure that this way of PL'n is not possible in the new MMO as well. PL'n doesn't just mean healing from outside of the party, it means a higher leveled character helping a lower leveled character speed level, and this can be achieved in many ways (only curing in FFXi though).
If FFXIV was like how you are describing then its the same as PL'n, but just inside the party and actually killing the mobs, instead of outside the party just healing.
This is why I think most guild leves will be instanced, because this stops PL'n in a way. If the Guild leve's are the primary way to progress (like they have said), and it is in the open world, then whats stopping you from getting a high skill level character from killing all the mobs for you and progressing at a super fast rate. This is the same as PL'n, just this time its inside the party, instead of outside curing. The point I'm trying to make is, PL'n doesn't just mean curing from outside the party (like it was in FFXI), but instead it means helping a lower level character speed-level, and can be done a multitude of ways. You just need to think outside of FFXI terms, in other games curing was not the only way to power-level somebody.
From what we've seen of the game, one-person can handle multiple equal-level mobs simultaneously, so there should be no concern over tackling whatever crowd with whatever party makeup; having more people just means the things die faster, without any reduction in each person's skill-per-hour; things dying faster should be no big deal if SE continues with the goal of vast sweeping vistas (and hopefully scales respawns to the number of mobs remaining in the zone); and party makeup won't matter, since your skill-per-hour depends solely on what YOU do.
I havern't really seen this, and the part that I did see where one person was handling a bundle of mobs, SE admitted that the characters was really jacked up. This means that the characters you see fighting was not basic leveled characters, and their level has been risen. They also admitted that the mobs they was fighting was very basic and lower tier type mobs. Putting two and two together, of course a jacked up (skill level wise) character can handle tons of low level or basic mobs. This doesn't mean you can adventure by yourself and take out tons of mobs. Matter of fact the part I read about the game said, the mobs was dangerous and wandering out of the town would be dangerous (I forgot exactly where I read that). I think there will be more of a reason to fight tougher mobs, then what you posted. Kind of like how FFXI is, a group fight around their skill level mobs, but with more group on group fights, instead of single vs group all the time. Edited, Oct 30th 2009 1:52pm by HocusP
