Let's see, before reincarnating I was addicted to lol. That speaks a lot about how he acts in stressful situations. Expecting him to act with the wit and cunning of a crafty MC is too much ... What if you wonder if you were in their shoes, would you do better? Here I only see a scared guy in an environment that is hostile to him. Making mistakes is common, the rare thing would be to have successes in a row.
I really dont like that these powers he gets are conpletely divorced fron lore. Yeah the heroes can do that, but by definition they also do a lot of other things that are not part of the main game. I hope these powers instead of just "Press button to attack" change to as long as a he learn how these powers work he should be able to change their power or even create other powers. I do like to point out that thr Powers he uses that are just mildy inconvenient to other heroes. Are basically one hit kill to a small batalion.
