From Funcom point of view, yes. From player point of view, nope. If you kept track of player reactions to knockback, not a single person saw it as ohnewcool stuff. Everyone saw it either as divine gift, or a doomsday weapon that will ruin their fun from the game. Players are looking forward and cheering up new content if it gives them an advantage. Players are complaining about new content, attempt to change it, or are sometimes even boycotting it, if its not giving them advantage.
Hell i'd really like you to show me 1 (one!) example of profession specific, combat related, content upgrade that was neither love nor nerf but made the game more interesting, because it sounds mostly like your theoretical construction.
Interesting and fun...for who? Can planting mines be any fun? It clearly cant. But i guess it easier to say to small minority of playerbase, shut up and go plant mines, it will be fun....for everyone else except you.
