My thoughts on Black Cleaver post 1.73:
Nobody is stacking it now. This is a great thing, and a huge step in the right direction. The instant you have players stacking one item over and over instead of buying one of the multitudes of other options, you know you have a problem. The Stack Cleaver was invalidating a whole chunk of items for a large set of champions, and that is not the case anymore in 1.73. So thumbs up on this end.
That said, it is still an amazing item and is still rushed on most AD casters because of what you get from it. Health, flat pen, % pen (for your whole team, in a way), and cooldown reduction all on one item is really, really good. I'll be honest, I still feel like BC is a bit too strong, but I think more of my concern lies with the whole penetration system and available sources of penetration, rather than just with Black Cleaver. Being able to combo Cleaver and Last Whisper, and THEN add in any flat pen from runes/items/masteries is what I think is too strong.
With the way things are working now, I would like to see % penetration reduced some more, so that when I buy armor (the intended counter to physical damage), it actually feels like a good investment. But that's enough about penetration, on to other things now!
Global Cooldown Aura:
The problem with Global Auras is that while they may give some help to champions needing it, you also give that help to champions who are already dominating Dominion, pushing them further out of line. I don't think this aura will do anything to help Dominion overall, but we are in pre-season so I don't necessarily mind testing it out for a couple weeks.
Thanks for putting these kind of threads up Nome. Shows that you really care about the health of this game mode, and I'd love to keep helping.
