Like I already stated, loot being taken from you is in no way connected to someone leeching though. If no on leeched then getting loot or not would still be an issue, and dungeons time taken to complete would still be the same, also as stated if you end up needing to revive the person you lose any time you gained, it takes like 5 seconds i think to revive a person, that's not even including the time spent catching mobs if they scatter. Unless I missed it I don't think you have actually addressed why these two points are not true, loot would still be an issue, and time spent could actually end up taking longer with more people involved.
What are you talking about? If there are more than 8 people and everyone of them does something to help someone that helped is not going to get any loot at all. How does someone leeching factor into that in any way? If like I said, no one is leeching it will still be an issue with the game. And if all you have to say about it taking longer is get good then you clearly have no thing clue what I was even talking about. If someone scatters mobs it's going to take longer to kill them all the Cheap Trove Flux, if someone dies that's at least 5 seconds wasted reviving them, and if you have a group of 8 or more people then time spent on a dungeon is a non issue since at least two people will be able to usually kill the boss in a matter of seconds before everyone else even gets down into the dungeon fully. Also, I don't leech, i am PR 15k and can solo U9 all day long with no potion stops so no, I don't leech.
Also, deserving of loot? Are you kidding? If that is the system we are going on then only 1% of the people playing would ever get loot. I one shot bosses in U9, if I did that and only the person fighting and "deserving" of loot actually got loot only, then no one else around me in the group would get a damn thing. Lets implement that system and have me follow you around for a day one shotting all the bosses so you don't get any loot and see how much you like the "deserving of the loot" system then.
If you go out on your own anyways why are you even stating your opinion on this? You clearly have no experience in the matter if that is the case. And the 1% thing was an over exaggeration but it still stand as a valid point. How many times have you seen people clearing a dungeon in half a second because they one shot a boss? Do you even see how fast some SH can clear a dungeon? If you were to implement a system where only people that help got loot then even fewer people would get loot than now. The actual number of people getting loot would be much less than 8 per dungeon.
My points still stand, no one has actually given a reason as to why they would not. No one has yet to explain why spending 5 seconds reviving and possible more chasing mobs around a room would not effect the time spent on a dungeon that you say would be faster if someone helped to buy trove flux online, nor has anyone given a reason why leeching directly impacts people getting loot when if you are in a group of more than 8 people someone was not getting any loot regardless of if someone was leeching or not. Not one damn person has given an actual reason as to why these two points are not valid and sound in reasoning.
If you want further examples of it, look at it this way. You have two groups of ten people, group A and group B. Group A has all ten people doing equal amounts of dmg to a boss, when the boss dies only eight of those ten people get loot even though they all help in equal amounts. Group B has nine people fighting and one person leeching, at the end of the fight two people still get no loot. In both cases someone that helped equally as much as everyone else does not get any loot for the dungeon, regardless of the person leeching or not. So how then, does a person leeching impact said situation in any way, if even had there been no one leeching the outcome would be exactly the same?
