Wow, where to start...
1) Nerfing monsters - are we really heading towards the casual players now?
2) Boosts to attacks & weapons - somewhat OK. Maybe it will be awesome when the crafting feature is done, but at the moment I'm reserving my judgement
3) The Blood Stone - *facepalm* Although its a good change, why wasn't it implemented earlier?
4) Slayers killcount buff - somewhat OK i feel, for those who like to explore/kill stuff for whatever reasons.
5) No more autocrits on helpless monsters - So what's the point of the crits system for? Where else is it going to work?
6) Spell change - still figuring this out, will comment in the appropriate forum.
Overall - why can't minor fixes like the Blood Stone change be implemented consistently per update, rather than leaving the problem in the dust for...4 years or so?
