My group has been having some issues with superior equipment. Although I kinda like the idea, spend a feat and get some type of extra whammy with your weapon, it causes issues as a campaign progresses. Namely that if you spend a ton of feats for a very specific weapon (or implement) you will forever be trying to get only that one type of weapon. Spenging $$ to make the one you have (PCs making their own magic items is another sore point with our DM) better or having your DM wave some hands and say "what do you know? another executioner's axe, but THIS one is +4. What are the odds?" We recently found a +4 Flaming bastard sword that is a key weapon in our campaign from a roleplay standpiont, but no one is going to use it because no one has that particular weapon feat. I don't recall any of my favorite sword and sorcery movies/stories/books having this problem.
I agree with the OP on his ponits though, Clerics having to use Int for their rituals has always seems stupid to me. Althoguh in general I am holding off on my opinion of the Essentials till it actually gets released. Sounds like they have some great ideas, but I have this nagging feeling that they are goiing to muck things up and create some quasi-optional splat material that will actually trump the core rules and D&D will become this hybrid rules nightmare. I'd almost prefer they just a "4e, no seriously" release of the core materials again with all the updates they've made with the feedback from the last 2 yeaars.
