The last time i played NWN & NWN2 i was bored of the enemies and got curious about their abilities so found out how to unlock Campaigns in the tool set than started editing all the enemies in all the Official Campaigns and quickly discovered that most have lame abilities, an example is a mini boss who i won't name in case someone is worried about spoilers this NPC is a
Fighter/Rogue Lvl 7
STR = 13 ?
DEX = 10 ??? (a Rogue with low DEX)
CON = 18
and Health is 135
NPC has next to no equipment and biggest asset is abnormally high HP.
Also most Mages in the games either have crappy spell selections or some have an illegal amount of the same spell to spam over & over.
this is just two examples and i could name many more but i don't wanna to spoil anything.
I went through NWN & NWN2 and found that so many enemies are lacking in proper Equipment Stats and Spells so i changed those by giving them maybe 1 or 2 Level increases and upgrading there primary stats and giving them at least basic equipment and made small teams of enemies who have a variety like 2 Fighters
1 Cleric & 1 or 2 Mages and so on so minions are actually doing something besides running up and hitting people.
I'm not saying we need to increase the difficulty to drastic levels but if the enemies have proper stats and abilities they have more tactics to use against us, i know minions are a bit like cannon fodder but do they have to just stand there and get slaughtered by us or could they try harder to survive a bit longer.
Also i gave bosses special equipment to give them a little boost and made them drop on death so the loot wasn't totally random and a little reward for defeating a boss is nice.
