I made this topic title pretty general, as I think there might be a lot of achievements-related ideas that people want to discuss. I know some people think that achievements are dumb and pointless etc, etc, (looking at you @Khizan)
, but some people enjoy collecting points, collecting the little rewards, etc. So here is a good place to discuss adding more achievements and rewards or tweaking existing ones.
For my own part, though, I want to talk about the three 10k mob kills achievements: Orc Smasher, Exorcist, and Vampire Hunter. As much as I appreciate collectibles, at least the ones for Chur, Rafe, and Balan have nifty catch phrases and that. I know for certain that the doll for Orc Smasher doesn't do much and isn't very interesting to look at, and I can't imagine the demonic statuette or the bone... thingy are any better for the 10k kills it takes to earn them.
So, instead of some crappy little collectible, I propose something that people might actually want for killing 10,000 orcs or demons or undead: some kind of bashing bonus against each type. It could be something like increased damage, or increased frequency of criticals, or increased damage resistance toward a particular mob type. I don't know. What do you guys think?
