Simply allow us to fully mod the game (and Explosive Arrows, Spells, Ground Effects, Hight Advantage, and Barrels are ALL able to be modded out) in every capacity, and no problem.
That could bypass some problems (though there are issues that modding might not be able to solve like reactions, as modding the original system in would require new systems and UI), though I never see modding as an answer to poor design or balance. Generally, I am unlikely to be willing to spend time designing and balancing my game after paying for it full price. If some kind souls will do that work for me, that's always nice, but it's a crutch not a solution.
And there is only that much modding can solve - for example in Divinity it didn't manage to fix the absolutely awful UI. Sure, "Improved Organization" is an alright concept, but it is fundemantally flawed, as it is in conflict if "wares" system. Generally, mods are small additions, not fundamental overhauls. Not many modders will have resources, time, commitment and skills necessary to redesign entire game. Especially, if the game isn't very entertaining in the first place.
Modding is great, and can occasionaly evelate games but it is not an answer to design problems. But erasing problematic mechanics, while the game was designed around them, will create a host of new problems players will need to solve. It's the same argument as "if you don't like it - don't use it!". That just not how games work.
