I have to be another voice of dissent here. Lend me your ears. I am a Witcher fan and I'm not saying this because I like it easy. I don't. You can challenge my mind all you want, but please don't make things tedious and please never give me clues that are 80% useful and 20% total BS.
Case and point: Baltimore's Directions
Start looking at the well, where loud echoes dwell
Take ten paces t'wards the river, walk left and do not shiver.
Meager two tens of paces, pass the gate in my good graces.
The one that our safety keeps. Go where the crossroads' patron sleeps.
Every road you need to take, yet the middle one is safe.
Heed and look for Ingrand's signs, and you'll follow my designs.
Should you choose to go right, you'll soon see someone in plight.
At noon this drowned soul, points its shadow at your goal.
First of all, there is no more river. It's dried up. No way would I ever interpret the destination as a river. Secondly, please don't use the word "paces" when you really mean a much larger unit of distance. Third, what gate? Fourth, which thing is the crossroad's patron? What are Ingrand's signs? Who is the drowned soul? The boat? It's hardly fucking drowned, because there's no fucking river. It's a puddle.
Tell me, and be honest, if you found this clue to be useful. I found the destination on my first playthrough. I didn't realize it was the intended destination until my 8th time through the game (or so). This is a horrible, horrible clue. It's not a bum steer (which is legit) and yet it leaves so much room for interpretation it could mean almost anything. Please, no more clues like this CDPR. None. Because if I see one dumb clue you lose your credibility forever, and I don't bother putting effort into the other puzzle quests because I also expect them to not make sense. I'm not the only one either. You risk losing your audience when you include stuff like this. There are even people on the web who liked TW1 but didn't like TW2 because they accused it of having modular quests that didn't intertwine the way TW1 Act 2 did. Why? Because they didn't bother finding that hideout.
The Baltimore's Nightmare quest was brilliant. It was original, dramatic and it tied in to other quests. Well done. But finding the hideout was horrible, and it's because of this clue. It wasn't lost in translation either. The Polish version sucks just as much.
While I liked the puzzles in TW1 (AFAIR there were only two--or three if you count the Blue Eyed Girl), I didn't like several of the ones in TW2, especially the Baltimore's Letter quest, the Gargoyle quest and the invisible ink quest (which I still haven't solved), and which suffers from confusing instructions and trial and error. I liked the lifting of Henselt's curse, or the thing you have to do before you meet the Operator, or the thing you have to do with Anezka in Act 2. Those quests only had moderate levels of trial and error and no misleading clues. I'd rather have no clues at all than clues like Baltimore's instructions.
