After 4E came out, well, especially after 4E came out, lots of threads would become back and forths between those who liked it and those who didn't. This derailed a lot of threads, led to a great deal of animosity, and, most importantly, got to be pretty tedious, so it was banned.
So no, if I think PF is the worst parts of 3.5 x 10, I don't go around insisting on that, or really say it all. I just don't post it.
This thread is a bit tricky, clearly people are switching for reasons, but "I like 5e better" is nicer and more acceptable then saying 3E, or 4E, or PF suck.
