At level 20 max ranks of 23, say +5 from con = +28.
Cross classed max rank of 11, say +5 from int (hey, he wants to be able to use spellcraft) and +4 from the feat = +20.
So yeah, not a great chance to overcome it, but possible.
So maybe it should be +5 and an extra +5 for everytime they buy it again. I was just trying to be weary of gishs who take it.
Useing BAB isnt a great way to go, because it isnt as good for some fighter types as others (such as monks, who likely should be better mage killers).
Useing skill ranks in spell focus isnt great because of the cross class rule, but at least it is slightly better than BAB. Most people are on the same playing field and it takes resources.
Like I said, not great, but definately better than the other way to go about it.
Just need something which takes resources to get but other types can pick it up.
Maybe the feat should allow the aoo with the check and makes spellcraft a class skill. That would solve most of the problems right there
