Please remove the 4h barter reset delay.

Who here is saying wagon trading shouldn't be buffed too?  Start your own suggestion for that, they are separate skills with different mechanics. 
Asking to buff one, isn't saying don't buff another. 

Parley needs removing completely, you are already time gated as to how much you can complete and capped with refreshes. Absolutely no need for Parley period. 

Weirdly, i see no one complaining about the price of the raw materials needed for first barters.
it was a huge nerf because we used to be able to barter 6 items for under 1m, now it's more 1m for 1item (and often unavailable on market)

Because you don't actually do mats->t1 barters in general, simple by doing cheap trash mats once a week you good to go for years of bartering. And you get 7 free  t1 mats in week from daily quest (1/d)

One of the major problems when first starting out Bartering was learning the weigh limits of your ship.  With the added number of Barters available this is going to be a huge stumbling block for many with lower level ships.  Also the lack of an ability to either place one item in your pack or destroy it to lower overweight issue is another issue that needs attention. I would like to see the following to help improve Bartering.

 1) Decrease the weight of all barter items by 100LT (This would allow for a couple extra items to be transported)

 2) Create a Barter node at Oquillas Eye

 3) Add a Storage Keeper to Quillas Eye so Barter items for Margoria Barters could be stored there

 4) Add additional higher level Barter nodes across the upper tier of islands IE: Crows Nest towards Oquillas eye and beyond.

 5) Decrease the cooldown for Barter refresh by half

 6) Set the minimum Crow Coin exchange for T5 items to 100 Crow Coins. Traveling to Hakoven for single digit amounts of coins is a waste of time and resources.

 7) Should a ship be sunk and need to be recalled allow barter items to be saved. It is bad enough having regen sailors and repair ship.

 8) Make quest Event: Bag and Tag Lema Island Sealife and permanent option at Oquillas Eye.  This is a fairly easy quest to help lower level ships work towards upgrades for carrying heavier loads.

 9) Add a feature for daily challenge rewards that would allow for a choice of normal item or one that pertains to Bartering, Ship Ugrades or Ocean content

Any other ideas welcome 

We don't suggested those changes. Furthermore they don't improve profits from bartering in any way.

1- Still same amount of parley and same cost of exchanges.

2- Still same LT of bartering items and same LT limit on ship

3 Still Same speed of ships.

Your system isn't even time saver as your GM's note's say ( if you kept them in), its still take same amount of time going from point A to point B.

It's not just lower level ships that are affected by the barter item increase, but nothing changed about weight. Anything not an advanced (and I guess balance) become overweight if the item multiplier is 3 and you do the full exchange. After ANY full exchange, valor and volante are forced to go back to port immediately or risk being overweight, adding needless time to bartering. Advanced was the pick you took if you planned on elongated bartering trips and/or overweight bartering. Prior to these bartering changes, it was completely possible for a valor and volante to exchange from normal all the way through to 5 and not become encumbered.

Bartering goods should have their weights drastically reduced. Invetory slots are already a good limiting factor, not to mention the amount of parley used doing a full exchange.

EDIT: Actually, just doing the full 10 exchange on a lv.3 to lv.4 bartering item always puts valor and volante overweight. The exchange that's probably the most attractive if you're doing CC runs for blue gear and nol. My suggestion is remove bartering item's weight or make them almost a non-factor. Parley enforces players to pick and choose how many of what items they want, but even if they pick the full 10 item exchange, they should not immediately be encumbered (as is the case for lv.4).

These bartering "buffs" are a slap in the face to the people that were wanting improvements; Personally I don't care as sea content overall is garbage and has been for a very long time. Just let us sell our ships to a vendor for a reasonable amount if you have no intention of fixing sea content.
