Thanks for the one for court approval, should make exploring the palace much easier.
Ok...could be wrong, but looking at your post...it's pretty obvious you aren't that far into the game. So.
Number 8: No. You are wrong. 99 of a crafting mat is not too much. It is not even close to being too much. Higher lvl crafting schematics can take like 20-30 of a crafting mat + the half/grip/legs/arm/blade/etc, and you can use 50+ of one type of crafting mat on a single item. Add in the fact that you are making gear for at least 4 people...yeah, 99 of a crafting mat is not enough. The last time I did a full craft/upgrade, I maxed everything out before I started & I still had to run back and max out my crafting items twice while crafting. But that's not something I think the trainer can fix (unless they can figure out a way to remove the step of selling/buying to lock in the 99).
The crafting mats without descriptions (wisps, etc) are used for a quest you get around lvl 8-10. The quest only needs 3 of them, so that's the max stack on those items. That has nothing to do with this trainer, it's how bioware designed the game.
There is no reason to ever sell/destroy crafting mats. Why are you doing that? Crafting mats don't take up inventory space, and there are sometimes requisitions/quests that require them.
Lastly, personal taste perhaps. I prefer number 9 to number 5...they both do pretty much the same thing. But number 9 is more controllable.
Anyway, the trainer is very helpful & does everything I want it to do. My only issue is that sometimes it takes awhile for number 8 to work (sometimes I have to actually scroll through every crafting mat for 99 to show up in the shop of some of the items), which gets annoying...but it always does work eventually. So
