I've been working on the pitchers all evening -so it's still going as we speak!
I'm adding all of the ones that have been done by Eric Chalek so it takes the count from 200 or so (many that split the NeL and AL/NL). It was a big bite - I think there are 600+ (so best to plan an expansion as they come in so there is room!). I am also updating everyone as the original was based on largely his 1.2 and 1.3 versions of the MLEs and this will be closer to his final version. I don't expect the mod to until Xmas - but it will be a significant upgrade from the original one.
As for OOTP26, they took the InteGREATed mod and treated the MLEs in a manner that, if an MLE stat line exists, it will read that when creating that years ratings. Presently, the pitchers are running hot imo. Much more so than expected as more and more people have given feedback. So, be aware of that. It's worth giving it a try though as you wait.
No better QA/QC than the community so when the mod is done, it will be release here so it gets a spin by everyone interested before OOTPD considers the revisions for OOTP27 (which hopefully they will, I can't speak for them).
