I'm playing at +35 and getting walks... but then again, I'm playing at A and have reorganized my own roster putting the worst pitchers at the lowest level, so I have no idea how it's going to effect AA and up.
Now, I'm not a very coordinated person and have always been bad at twitch/timing games... MVP is no different. At +35 (which I figure is roughly equivilant to setting the slider at -75, if it were possible, without Spitoons walk fix) I'm throwing probably 1 mistake pitch every other inning.
Now, beyond that, I do have some commentary... Playing in this manor creates a dimention of realism that simply does not exist otherwise.
Most MLB pitchers... when I say most I'm excluding excpetional ones, so don't start making Radke arguments against me here... cannot locate a breaking ball with a whole lot of precision.
Through technique they learn to keep the ball down in the zone, but they're not going to look at a target and hit it most of the time. Very few pitchers have mastered the art of locating a curve ball... which is why it is not standard practice to have the catcher call the location of anything save a fastball of some kind... no point in telling a pitcher to throw a curveball away if he can't decide where the heck is going anyways, and making him try and throw it outside is most likely going to result in a wild pitch.
At the level I am currently at, I can only be comfortable making slight adjustments to the location of the pitch from center. You can't go for corners (high away, low away, low in, high in) with any confidence really, you can only hit sections that are abutted by 5 other sections (outside, inside, high, low)... having more adjescent squares means more room for error. This is a more reasonable immitation of what MLB pitchers do with pitches they are less able to locate.
Now, most MLB pitchers CAN locate a fastball... this is fine, because most pitchers in MVP have reasonable control ratings for fastballs and the fact that fastballs are easier to locate seems to be included in the code to some extent.
I'm really enjoying the pitching as is... I'm having a rough time of it, but I'm chalking that up to my own lack of skill unless it persists despite my improvement over time. I figure I'll make some slight slider adjustments once I complete my first month of the season.
