Gaxel: I agree, but all the info you need are in the manual and in the tutorial section of the Journal... you only need to find the time to read... if you're not so lazy...
ilves: I read the manual. Reading the manual to understand what buttons do does not translate into how to actually fight though. Tactics, how to approach enemies, etc, are not in the manual. Plus changing targets in mid-fight is aggravatingly difficult. You could, if the camera let you, attack one target, get your next swing on an adjacent target and keep them off balance, but the targeting doesn't allow for this as much as it did in Witcher 1.
The manual says that you should use the fast style against weak enemies, and strong style against enemy wearing heavy armors.
It says that you should use block against enemies carrying a shield to counter attack
It says that you can launch bombs using auto-aim mode or aiming yourself and should be use against groups of enemies
It says that daggers are useful against weaker opponents.
It says that you should drink potions before a combat
It says when you should coat your blade
It says that you should use your medalion to spot place of powers that provide additional support on combat
It says when and how you should use all the signs
and many more...
Beside that, you have a complete tutorial in the Journal that explain all the thing not covered in the manual.
I agree that the tutorial should be more user-friendly, but it's not that bad.
