That's my point exactly. OK, the killer used a weapon that leaves a residue that blocks every spell. That makes a murderer investigation possible, but now you've got a player with a reasonable complaint that you've just neutralized his PC.I was going to counter with the idea that the dead might not know for sure who killed them. But from a player's point of view, blocking the use of their abilities for contrived reasons can be pretty frustrating.
And that is just one tiny example. As pointed out, you've got much more invasive spells, talents, and abilities which eliminate extended non-combat interaction.
I'm all for PCs developing abilities which made them more effective in non-combat and combat situations, but there still should be room for player innovation beyond that of memorizing an ever-growing list of illogical abilities.
