Yea red line drops a little fast but your biggest problems are preflop. You limp or call too often, you don't raise enough when opening, you don't threebet enough which allows players to fold correctly because you always have a great hand, and when they don't fold they have enough implied odds knowing you are stacking off to sets and two pairs way too much.

Your W$SD% is about 50% meaning your betting needs work, and you check/call way too much.
