You don't have to min-max, you know. That's Munchkin behavior. It should be enough that a character is interesting and fun to roleplay.
If you speaking about IRL games with people, - maybe. But, no offense, who cares about PnP geeks and their so-called "roleplay". in C(omputer)RPG? If you wanna "roleplay" why you play games, why just not going to DnD-club to "roleplay" with you friends? Character optimization is essential part of PC gaming and CRPG. Also I said nothing about "min-max". I just said that Paladin in DnD is Leader of a group, it is strange that "Leader" is not required INT.
