First of all thank you for your reply! I found the maximum target option and it seems the bot is not dying as often anymore. Also seems that it works best with mobs that are of the same level or below. Changing the food value also helped. I am honestly not bothered by paying more for food. So thanks again.
The selling and mailing issues seem to happen because the bot tried to mail quest items, conjured items and anything else that can't be sold or mailed. So the bot would try over and over for quite some time before stopping to mail or sell altogether. I guess this can be fixed by adding the items in question to the not to mail / sell list.
In the end I think I was able to fix some of the issues and by pretty much creating my own profiles.
As for improvements, I think there are too many things you need to set and include / exclude. I know there is often the need for some tweaking with bots, but adding specific types of foods here, what to sell / mail, there and so on. It just seems there are quite a few options that could simply be excluded by the bot in itself (not the option mind you). There were other things, like the bot mailing the skinning knife or the mining pick. It is just frustrating to come back every time and the bot has been doing something weird. I hope you understand what I mean. I think by now I figured most of these things out, but it took my quite some time.
Another issue are profiles and fight classes. I don't really like to compare the two for obvious reasons, but Honorobuddy came with routine (Singular) and a full fledged set of leveling profiles, making it possible to install the bot, press start and let it run. Now I am well aware that this would probably way too much work for Droidz, but I think the bot should at least include some rudimentary grinding profiles. I know there is the Automaton option, but that too was acting strange at times. In general I think the basic bot should include some more features.
I kinda got things to work by now, but it was very frustrating. I have joined the discord as well and was able to get some answers and some help. By now I got the bot working pretty adequately. I think it really was mostly profile issues and quite a bit of tweaking that was necessary.
And I agree, I think a wiki or something would be a great place, but as said again, that would be quite a lot of effort and I can see that Droidz has other priorities.
