Hey, this GOW is really addictive, and excellent ! I'm still playing it slowly. So you already beat the full game ?
Some of the boss/mini-boss fights are too tough though. I find the beginning hours to be frustrating with limited capabilities and resources to deal with the sponge enemies. Other than that, it's a lot of fun and I like managing everything. I imagine as I level up more and unlock new skills, it'll begin to balance out for me.
Well, like I said, I beat the campaign, but not anywhere near the full game. I had only about 50% completion when the story ended, and I've still only defeated 1 of the 9 Valkyries, and the hardest one, the Valkyrie Queen, is very tough.
As far as some enemies being sponges, are you attacking their weak spots? For instance the Soul Eaters only take damage when their chest opens to shoot fire or frost at you, the open chest being the weak spot. I found even the one in the forest near the cave where you look for Sindri's whetstone is not too hard if you just stand behind a big tree and step to the side of it and do a heavy axe toss, then step back behind it. You can either keep doing that, or grab the parts that fall off it and throw them at it to take it down much quicker.
Another thing that can make some enemies feel like sponges is if you use a weapon that is useless against them. For instance hell type enemies like Hel Walkers, the green ones that are basically zombified Reavers, are best dealt with hand to hand vs the axe. You need to block, or better yet, parry their attacks, then get in some good punches and shield strikes. My video above called The Sickness - Battle at Home, is a prime example of how long it can take if you only use the axe. That was before I knew best how to fight them.
There's a simple core theme here, Hel creatures in this game are from a frozen world, so are very resistant to the frost axe, but they are easily damaged with the fiery chaos blades, and less so, punches, kicks, and shield strikes. However enemies that are fire based, including ones that actually shoot fire, are easily damaged and frozen by the axe.
There's a narrated video guide I'm watching lately by All The Shinies on how to beat it on Give Me God of War, the hardest mode. I learned a ton from him, mainly which weapon attacks and armor enchantments work best, and how to knock enemies off ledges or into water.
Where you position yourself can also make some tough battles a LOT easier. The 2nd dragon I freed had a tough fight with witches and heavy draugrs, but I found if I ran to the far left from where you enter, just to the left of the dragon, they would mostly avoid me while I had Atreus sling arrows at them. Once he had them stunned and weaken pretty good, I finished them off with axe throws, then up close runic attacks. So buy all Atreus' skills, it helps a lot.
There's one thing I really hate about the game though, and I suspect it's due to it originally being made for consoles, and the gamepads they use. That would be their insistence on using ONE single binding that has to be used for both block and in conjunction with 2 other bindings for light and heavy attacks. On keyboard, that binding is Q. I thought I could easily solve the problem and free up my move left finger if I bound it to one of my mouse thumb buttons, but as it turns out, holding that thumb button and L or R mouse button at the same time for light and heavy attacks feels really awkward. It's a shame too, because the mouse button by itself feels fine for blocking or parrying, especially when moving intermittently in between as you often have to, but it's causing me to miss a lot of light and heavy attacks and get hit. It's so annoying in fact that it may very well be a deal breaker for making a walkthrough unless I can find a better solution.
