I know many people on MUT choose to run the ball on conservative all game, and it makes sense, especially if you aren't as confident in your stick skills.
However I feel like the penalty is way too light for such a huge advantage. You can click a setting on and make it basically impossible to fumble? That is ridiculously OP. I remember back in the day when you had to run smart, make someone miss, or hold protect ball! and if you failed, well that was on you.
Now EA makes it so people can swerve around like a chicken with their head cut off and have virtually no risk. It isn't good for the game, and it is very unrealistic.
I would suggest that if someone wants to turn fumbling off, they should also lose agility, change of direction, and speed. So yes, you can run in a straight line pretty much full speed, but if you want to protect the ball you won't be able to cut nearly as efficiently. I also think you should not be able to break tackles at all with conservative on.
Let me know what y'all think!
