So, probably going to get ignored/it's too late... but I hate the thieving mechanics.
Issue 1. Single pickpocket opportunity the entire game. That is ridiculous. I didn't like it in DoS:EE, and I don't like it here. If I pickpocket someone at lvl 1, now they are permanently off-limits to me the rest of the game... why? If I now have more skill at pickpocketing, have greater dexterity (finesse), why can't I pickpocket them again?
Solutions/alternatives:
1. Timer. You have to wait 4 hours of play time before you can pickpocket them again.
2. You can't pickpocket them until you have a new level in thievery or at least 4 more points in finesse.
3. Alertness. After the first pickpocket, they become more alert, making it harder to pickpocket them. Requires greater skill and dexterity, becomes harder every time you successfully pickpocket them.
Issue 2: New to DoS 2... now, not only can I only pickpocket them a single time... on top of that, they magically figure out it was me (even though I was successful) and now demand to search me...

So, not only do I get 1 single opportunity, I can STILL fail, if I can't talk them out of searching me... RIDICULOUS. So, even though I was successful, they get an automatic, 100% chance to catch me...
Solutions/alternatives:
1. Any and all options above.
2. Only a very limited number of characters should be able to search you or even request it. Is some random shopkeeper REALLY going to force a confrontation which will likely lead to their death over 40 measly gold pieces? Because right now, the answer is yes. If it is a high-ranking NPC, maybe they could have this ability. But, normal NPCs shouldn't.
Don't double-penalize me for picking a rogue. Make realistic game balancing decisions. Either legitimately include thievery or remove it altogether. Don't make it a useless skill that there is no point in investing in because you can only use it a single time and it pretty much is impossible to do without being caught.
