Finally made it into D2 last night. I have got so close a couple of times, but finally made the jump up. Made a few minor tweaks to the tactics, and changed a few players and its all
D4 was comfortably the worst division I have experienced so far. It is literally the sweatiest of the sweat. I think mostly because people have had such a tough time in D5 with so much of a wide scope of skill level (some elite level players like to hover round d5 for easier rewards) that d4 rather than becoming a place to then relax and enjoy the game, becomes a place to feel a lot of bitterness towards the game.
D3 on the whole was so much better. A lot more people skip celebrations, and try to outplay their opponents rather than sit back and defend with 8 in the box hoping for a counter (it still happens, but rarely - most people in D3 are decent at breaking down a deep defence with patient build up, so sitting back is asking for trouble).
