There are several problems with this. Obviously, the players who actually put time and effort into playing the game fairly will and should feel a little disgruntled towards those that are too lazy to actually play. That being said, there is also the issue that power-leveling parties can easily out-pull a group of appropriate level characters. For example, an rank 50 archer can pull several mobs at a distance and then use arrow helix and clear an area very quickly, (even though killing one by one is better. Yellow Name = no SP!). The point is that a group of players who want to legitimately level in the area could not possibly compete with the killing rate of a power-leveling party. Which leads us to the next issue:
If SE ever wanted to address this problem, they have to be very careful about balance. Mainly that even though the lazy players, (that will have no actual skills at playing the game), are getting SP, it's the rank 50 that is doing all the work. There is no rule that says a rank 50 can't go back to a lower level area and kill mobs. I did this quite a bit in FFXI to get drops, such as beast blood, or silks, or what have you. I think the reason it was more acceptable is because no one was trying to get experience from these mobs, so the only people who could complain about it were other competitors.
The other problem is that if SE acted too hastily, (they would never do that, right?), then it could have serious repercussions on larger parties. I'm sure everyone has been in a behest or some other large group, and realized that they couldn't even get an attack off before the mob died. Even though the intent to participate was there, the fact remains that the player was a non-combatant. I'm also convinced that, (if addressed too seriously/quickly), it could serve a problem for healers. I play THM mostly, (dragging my heals to level CON. Don't know why...), and I static with a Gladiator. Occasionally we have a LS-mate who is an archer play with us. When all three of us are together, I mostly just heal. I could throw out a bio or poison, but what's the point when the mob dies so fast? I played WHM for a while in XI, so healing isn't a problem for me. But I think if SE tried to return to the "you must hit the mob first to get SP" mentality, it could be a major problem for those who are present but not directly in the conflict.
Aside from this, I have to pose a question. Is Power-leveling morally wrong?
Now before you get your knickers in a bunch, let me explain why I'm asking this. I feel that XIV is far too easy in 80% of its content, and that power leveling isn't necessary. But in FFXI, there were quests and missions that were very difficult for players at the level in which they got them. I can't count the times I got help from my LS to do things that a party at my level would have issues doing. Getting the keys for Kazham, getting an airship pass, or even my Artifact gear. I was always very thankful when a level 75 would help me out. But in FFXIV, quests can easily be solo'd. Grinding for experience is relatively easy, and even then the leves and hourly behests are normally enough to keep me from needing to grind.
But even if we go back to Valkrum Dunes, I think anyone would be hard pressed to find a player that didn't want to hurry up and get to level 20. I've even been out there to help my LS level faster. I can't help but think that power-leveling, (or using higher level jobs to complete content designed for lower levels), isn't really "wrong" in FFXI. But in FFXIV, everything is so easy that I find it lazy. Maybe it's because in XI, the lower players still had to work? But I just feel that the only people who would be dumb enough to look for power leveling in XIV are going to be RMT of some sort. Any player worth their salt wouldn't even bother with power leveling.
Conclusion-confusion: How would SE be able to stop party members from simply leaching SP without breaking the larger party system? (I know the obvious answer would be level difference, but to **** if I know what they think about that). And how does one deal with the fact that this really isn't an exploit? They aren't cheating or hacking. They're just using the rules that SE gave them, and trying to find the most elaborate way of getting out of actually playing the game. (Which begs the question, why play the game if you don't want to play the game?) Yes, they aren't playing the game the way it was intended to be played. But if it's legal, then it's legal. ***** lawyers). Even then, moral issues aside, it isn't SE's job to dictate what can and cannot be pulled based on levels. I think when it boils down to it, it is still simply competition for the limited resources in the area. If it were a solo BST in XI or a power-leveling group in XIV, it still just another player getting the worm first.
Do I think it's right? No. Obviously not. But I am not sure that there is anything that can really be done about this.
