It’s more that Phantasm (specifically) is treated as a pet, which wasn’t really ever intended, but also isn’t something we intend to change. As always, we’ll keep an eye on odd interactions and make changes if something goes bananas. 
More than a little accurate. I generally find that people are very vocal about necessary nerfs until they’re relevant to the class they play the most. Funny, that.
(Not everyone, of course, but there’s certainly a trend.)
We’ve been pretty vocal about intending to do something about Bazooka for a while now. It will kill some playstyles that a fair amount of the community seems to agree is unhealthy for the game and doesn’t feel great to play.
If it leaves Wizards so far behind they need more help, well, then we’ll give them more help. We want everyone to have play styles that are strong and fun, but don’t require debatable use of game mechanics to accomplish.
