Maybe encounters should reward a fixed amount of exp (valid even for "diplomatic solutions" rather than going on a kill count basis? I've always preferred goal-based exp rewards to granular ones, anyway.
P.S. Not to mention that "enemies attempt to flee" doesn't have to mean "You'll let them do it".
They do. I want to say this was implemented last patch, though I could be wrong.
Just as an example, the group of adventurers outside the crypt at the beginning provide 50 EXP if you convince them to leave you alone and not engage in combat.
Yeah... That's not what I'm talking about.
I'm talking about the fact that you should, for example, get a fixed amount of exp for getting rid of them regardless of how you do it.
Currently fighting them pays significantly more.
Not to mention that you can get rid of them with "diplomacy", force turn-based mode as they are leaving and STILL kill them and get the kill exp reward, too.
Sure, for once is the kind of min-maxing you need to actively search for and not a particular vulnerability Larian has implemented over other games of this type... But still, a temptation for the player that could be entirely sidestepped if there was ONE exp reward, period.
P.S. I'm kinda hoping for a chance to meet these guys again in the final game if you let them go alive, as a side note.
