Ok, the battle system is shit. Dodging sucks, sometimes you hit the wrong target even though I'm locked on. Good thing that this game has a great story or I wouldve shelved it.
Don't lock on, except for maybe single enemy boss fights. Dodging is really useful against monsters, just try to time your dodge so you can go completely behind them. Also don't forget that you can roll out of the way. The hitboxes can be questionable, but I am loving the combat in this game.
Also, don't do the Mysterious Tracks quest at level 15, even though it will turn green. It is a level 20 quest and man, they mean it.
I love accidentally discovering places only to find some amazing rewards. I freed some guy from some bandits and it turns out he was a swordsmith. Who cares right, I already have Hattori. However, he sells the crafting recipe for the Superior Griffin Steel Sword. That was a surprise. The last dude I saved was a barber (why would you kidnap a barber?). I also accidentally found almost the entire Superior Ursine set diagrams in a random cave. Speaking of caves, I wandered into one only to find two guys hiding out. They were trying to escape a monster, and I immediately got a new witcher contract. It's great that they're not all tied to sign boards. Speaking of monsters, I've encountered several brutally tough ones that are way above my levels. I saw a cocatrice harassing sheep, a level 22 fiend guarding some chest, a gargoyle who looked easy but yet somehow has the ability to jump fifty feet in the air and throw rocks at you, a lone golem in a cave THAT WOULD NOT DIE etc. I like how enemies change their look when they get to a higher level. Drowners get fins, nekkers get these skull helmets, ghouls get ghoulier etc.
Right now I'm level 15 and rocking the entire enhanced griffin set. Looks like I'll stick with it for a while, since my other crafting recipes are several levels above. At first I didn't notice merchants leveling up with me, but some in fact do. Especially Hattori. At about level 14 he sold the blank runestone diagram and is now selling greater runes for outrageous 1000+ coin prices. YOU OWE ME A DISCOUNT.
