This huge nerf was uncalled for.
If any of you has spent more than 5 minutes in the forums you'll have noticed how they have grown a lot in the last couple of months, with a lot of both new and old people signing in (possibly due to some mentoring program in the latest week), and if you care to know what these new folks think about the game, you'll hear thing like "too much grinding", "the game is too slow", "not noob-friendly" and even others like "upgrading is too expensive", "grinding is boring", etc.
While most posters in this thread might have been playing this game for so long they have by now fully upgraded card collections, new players shouldn't have to keep up with your stubbornness, and they should have a chance to have fun playing this game. Why was the best FG farmer (since sundials, which were OP, I agree) killed? Because a +1 cost nerf was, surprisingly, not enough to counter the existence of a deck with a winning rate close to 60% which, by the way, wasn't even the best FG farmer at the time.
'Nuff said
