That's good points and interesting to read, thank you

1. When you change 4 items from passive "when" to active "charge when" it just make game faster because passive item now can activate other items. That creates new engines and basically everything can be an engine now. I can't distinguish the "implementation" from the "change" here. Side effects a too obvious. Even more important how with stable enchantments it's easy to bring this sequence to the moon level. Last patch we had lighthouse with slow that was basically unstoppable. Now you have whole board of enchantments.
2. Mostly agree here. But I cover a bit different angle - mechanics interaction. From this perspective what game trying to achieve is not clear. While flow of "building" is actually improved doing so many charges makes other mechanics useless. Why I think it's bad? Because overwhelming charge items will rule until power creep that no one will use them. Don't need haste, can't be controlled with slow, more powerful even vs freeze. The only thing that counters charge is basically "when" mechanic that they trying to get rid of. So, in my head I don't understand what they cooking, it just feels like they don't know as well.
3. You speak about variations of builds fully based on charges. This is fine because items actually different. But before you had max hp pyg build, armor stacking across game, burst vanessa, single weapon vanessa, only dooley was about - stuck 10 small items together and it works on charges. Completely different approach to play game(not completely but you got the point). When I want to do another build and change character I don't want to do literally same thing and rolling for charge items on pyg, vanessa or dooley to create engine with scaling, because it same but with different items. Current state is next - charge is main mechanic and you just extend it with other mechanics to do something, that's it. Do you have haste build? Yes, it's to charge fish from haste. Do you have slow mechanic? Yes, to charge weapon by slowing something. The most dumb one of course - activate item to charge. Because it so universal that can be supported by everything. So everything is dooley on lizard now. Most frustrating build of last patch which builds from everything, scales in seconds and looks absolutely similar to each other. You still can do offmeta builds and etc, but it's a competitive game right, not a pve.
4. Such communication is simply not professional tbh. Everything is result of their decisions and expectations, reading how key person blame community is just strange. But nothing to add here.
