Totally, i do totally agree with getting rid of surface effect mechanics, it totally break inmersion.
For me its like putting lobster in a steak. Do I love lobsters? Yes. Do I love steaks? Hell, yes. Do I want to have a steak/lobter hybrid, helll no.
Let move the surface effects to DoS III. and let BGIII as D&D 5E.
First, I would LOVE a lobster/steak abomination.
Second, surface effects just make sense. If you are sitting on a barrel of gunpowder and someone shoots the barrel with a flaming arrow, you're going to go boom. If you light Grease on fire, it burns. This just makes logical sense. One of the reasons you don't like it here is because we have been presented with Uber Goblins, all of whom are holding Acid Flasks, Alchemist's Fire, Flaming/Frost/Sonic Boom/Shock arrows at first level. That's just silly. In DOS2, I hated the fact that because I had a character with Glass Cannon feat, that every single encounter, no matter where I placed her, began with her being attacked. The same is different but true here. Every damn one of these goblin encounters starts with them hurling fire, Grease, acid or something else to debilitate you immediately. They need to cut that shit out and let Gobbos be Gobbos.
