As it stands, even gun people might be tempted to go for a class with melee combat just for the increased attack rate.
Sure, and there's nothing bad about that. There is no minimum STR, and certainly no maximum DEX, prerequisite for those classes, and none was intended. Even a weakling can take a level of strong hero, and I like that.
If you want to have a real high BAB, by all means go for strong hero, even if you have STR 8 and will never use a melee weapon. After all, it means that you'll miss out other stuff: More Skill points, Talents and Bonus feats that will actually use your other ability scores (DEX for example) better, and other stuff.
If you go for strong hero instead of fast hero, you'll miss skill points, a better defense bonus, stuff like uncanny dodge, evasion and defensive roll, and so on. If you go martial artist instead of soldier or gunslinger for your gun user, you'll get class abilities you'll probably never use, and will miss stuff that could really help you, like close combat shot, weapon focus, bull's eye, and so on. a good BAB is not everything there is if you want your character be good at gunning (hitting's only half of it: you want to avoid getting hit, too)
