Agreed.
Maybe there are more examples you could have used OP, but if someone is asking for feedback on powers, I don't think it's fair to say that people should pretend they have a wholly positive experience. I'd really hate if I asked for feedback and seomone gave me meaningless positive plantitudes. I know that i can do all the content with most powersets, it's about the ease of doing so, and what level I might be able to do it at.
Ultiamtely, if it is not against the ToS/CoC, they CAN say what they want. Being overly negative about powersets is not against either of those documents. It's hyperbolic, but ultimately it's just people's opinions. People can discuss how things would like to be changed even if those are done by another server, its a useful metric because it goes someway in showing what *is* possible.
I also have no idea why the fact that HC are still negotiating should be mentioned in these sorts of discussions. I'm glad they are, but its really just not relevant.
