The combat to begin with in the first chapter is frustrating. I died more times than i could count - not even taking into consideration the boss fight. After completing the game once and replaying it, i found the combat much easier. I still have the same basic equipment, but i can handle the fights much better - so there is a learning curve to the system. It is more action based, but it's still a good RPG.
Nearer the end of the first chapter, you will be able to get some new equipment which helps in the fight, but you do need to use the Signs like Aard, Yrden and Quen. Quen is essential in a large group, it stops you taking damage. You use Yrden to trap mobs to keep them at bay and Aard to push back and throw off balance (if you find a ledge, you can Aard things off it). You do have to dodge a lot as well, attack, roll, attack, roll, keep moving.
There is a lot more strategy than meets the eye, it's just, it doesn't tell you how to fight, it kind of expects you to know. Getting the reduce back damage skill is pretty much a must too. By the second chapter, most of your combat woes will be gone as you get the decent equipment.
As a hint... in the early stages, concentrate on getting Vitality, through the trophies and item enhancements, like with the diamond armour plate and Earth runes, they make a big difference (and the +100 vit from the skill).
Edit: Forgot to mention, when in game ,you can turn Difficult QTE off, meaning, they don't occur in game except for fist fights - but to be honest, QTEs are very rare outside of fist fights.
