Also, Mearls tweeted that bonus feats won't survive long.
If what Mearls' tweeted ends up being true... then bonus feats are to this packet when the 11-20th level Martial Damage bonus was to the previous packet-- just a placeholder to keep design balance in place until a better system gets installed. I have no problem with that.
Things like Charge, Bull Rush, Disarm, Pick Pockets, Open Locks, Disarm Traps etc. are all in a weird place. Some people believe that any class should be able to attempt these things, whereas others think they should remain the province of those classes specialized in accomplishing them. At it looks like with this packet they were trying to avoid doing what they had in 3E. In 3E they had these abilities open for everyone, but they were so damn difficult to actually accomplish without taking a feat to specialize in it that they might as well have not been available to anyone. If you wanted to trip someone in 3E... you pretty much had to have the advanced feat to make it at all worthwhile.
Thus this packet just cut out the middleman-- they just said if you want to do these "difficult" maneuvers... you need to be trained in it via a feat. Otherwise don't bother cause it ain't gonna work. And I can certainly understand that. You want the Fighter and Rogue to be special by giving them stuff that no one else can do... but then half the people complain that their "immersion" requires anything non-magical to be available to anyone to try. At some point though... you have to say enough is enough. Sure anyone could try to do maneuver X-- but if its so damn difficult that no one ever will try to do X (without the feat)... then why bother even putting the option out there? It's a lame attempt to placate everyone for no tangible results.
