TLDR; If people are unsure of something being an exploit, it should be made clear. Rather than let some people "win" at the cost of others, or ban a mass amount of people.
Back when I played ffxi, there were two major exploits that really screwed up the game.
The first was "Rusty Cap Fishing" in Rabao. Essentially people botted rusty caps for months, sold them to an npc, and flooded the economy with gil. After this the in-game economy tanked.
Many years later, people figured out how to duplicate items dropped by a boss. People did this for months and at the end 100s were banned (and many people lost friends)
When ffxiv started, people exploited a cnj healing bug which gave them massive amounts of exp. Within days they were rolled back.
However, since 2.0 launched, we have had issues like speed running dungeons and locking out trains of mobs, jump-hacking (when you took no damage while jumping), glitching bosses to do no damage, win trading in pvp, and probably more.
Many of these have been significantly debated on the forums, with no clear answers (some like locking out mobs did get an answer).
When people are winning any form of content by clearly glitching the system, there is a serious problem.
When people are doing it publicly in duty finder, you get a culture where cheating/exploiting is an accepted part of the game.
The only people benefiting from this is those who are exploiting.
PvP Win-trading is the best example of this at the moment.
This consists of people creating 2 groups, removing all their gear, and entering at the same time so that they can take turns insta-killing each other.
This happens in many other games, and people are generally banned or rolled back (SWTOR for example)
There has been a thread on win-trading in the PVP forum for 4 months now with no answer. There is currently a 26 page long thread in the general forum on the topic, going on for 10 days, with no answers. Other threads on the subject have been deleted. If you send in a support message asking about the question, they will direct you to the forums.
Now you might say "who cares"
Well, some people are using win-trading to get to rank 40 in a few days
Others are spending weeks waiting on 30min+ queues and fighting challenging battles (or getting their butts kicked) in order to accomplish the same thing.
How is this game fair if some people can accomplish a goal (by what most people would consider an exploit) 40 times quicker than others?
I'm not saying SE should ban or punish people.
What i'm asking is that if there is a potential exploit, and people -regularly- debate it on the forums (e.g. 20+ page discussion) a dev/gm/mod should Clarify The Issue
If they say "sure go ahead and do it" then everyone can play the game equally without a fear of a ban.
If they say "no it's an exploit" then people can be comfortable reporting it (without feeling like they are wasting someone's time). And knowing it's a bannable or punishable offense might stop some people from abusing it.
I'm not saying anyone should be banned/punished or treated special. I'm just saying, the game should be equally fair for everyone.
I hope that's not too much to ask.
