Honestly? Tw1 was easy because it was easy to exploit the combat. In tw1 you have infinite igni spam that kills everything. In tw2 you have roll and quen, quen was kinda fixed, roll should be linked to vigor like parry. What i would like to see in tw3 is more bossfights like operator - it was easily the best designed bossfight in tw2 and it was optional... And more balance, it was kinda there in arena mode. What was wrong in tw2 gameplay is that it's challenging at begging and challenge (except operator fight)is gone for the rest of the game because geralt is too tough.They should make everything past chapter 1 way tougher to keep up with character progression.
Kayran: unnecessary qte, too scripted (I know you tried to make it epic)4/10
Endryaga queens: kinda there, too bad they where easily hitlocked if you spammed them on the back, make them turn around faster so you can hit them twice and that's it also next time fix trap stacking 8/10
Letho: It was ok bossfight for first playthrough but if you figure out aard and 2 heavy attack combo then meh... 7/10
Draug: Too easy, kinda fixed in ee but still too easy 5/10
Operator: as i said already best bossfight in the game 10/10
Dragon: too scripted It feels like you couldn't fight this thing in any other place6/10
second letho fght: Too easy for high end geralt 4/10
Also let's rate normal mobs:
humans (and other humanoids): mostly ok, if you mastered parry and riposte in main game they become trivial (arena encounters were way better balanced), also no tough human enemies, if you fight 1vs 1 you are 100% sure you win, in tw3 put someone like bonhart that could rip your head off and **** down your neck. 7/10
Neckers: nothing to say really, decent enemies in pack 8/10
Endryaga: another decent normal mob 8/10
drowners: in pack really deadly, disable that jump attack, we don't need to roll more 7/10
harpies: waaay to easy, you can just hack and slash through them without thinking 3/10
Rottlings: drowners exploding after death 7/10
golems: golems where decent, little to easy, make them faster 8/10
warewolf: this is really good mob, shame that it appears only once, i would put it in chapter 1 and more of them, that should be fun. 9/10
wrights:all wrights are great both soldiers and ghosts 10/10
draugirs: are ok 8/10
im sure im missing something, first off MORE MONSTERS, bestiary in tw2 is pathetic compared to tw1, where are kikimores? where are ghouls etc.
What i liked in tw1 more than tw2:
Armors, in tw1 you have 3 armors in whole game, it makes more sense than changing your armour every day, just make it like in gothic games, put 8 armors and if you chose some path you get one armor and if you chose anther you get different. Also why can you suddenly carry more than 3 swords, just bring back tw1 system, it was more fun to manage your equipment. Alchemy system, god it was so much better in tw1, first make potions last as long as in tw1 second potion making with alcohol base. Drinking while meditating is ok tho.
