This game has steep learning curve, and that's good (MP). It's far from one hit kill, no matter how hard you trying to say it is.
I have to agree. People usually die from one hits if 1.) They get a solid couch 2.) They get a birthday to the face 3.) they are unarmored/tissue armored and they get a strong birthday to the pants 4.) An Ogre build decides to give you a hug.
1.) Couches are easy to avoid once you have even a mild grasp of the game and are paying attention (If you are not paying attention, then you get ganked, even from a guy with a rock this happens, welcome to life).
2.) When someone donates an implement of destruction to your face, it should be rewarded with massive (often lethal) damage. This rewards skill and luck, like practically ever game does with headshots. I see no problem with this issue.
3.) Armor is for a reason, and a carebear swinging 21 STR 7PS sword to your chest should leave a massive impression on your life, yes?
4.) If an Ogre build decides to bless your body with a 2Her, then you very well should die from that hyperspecialized character if he hits you with a solid hit and you do not have a top-tier armor and/or a lot of hitpoints with great armor. His disadvantage is that he lumbers around and his low agil and other things make him easy prey to agil-trolls and bolts and arrows and thrown bananas. I am also ok with this.
Yes, when someone OS you, then you will remember, but with all due respect, the vast majority of your deaths once you have a higher level
balanced character (If you have a hyper specialized or lightly armoured character, then shut up about getting easily ganked in melee, you should be aware of your sacrifices so play accordingly. A glass cannon is a glass cannon.) you should be dying from two to four hits. Well armoured or fighting against weak foes will extend these hit amounts.
