I don't know if you played q3 but the way the maps are played since QL is drastically different. DM6 was a fantastic map for q3 but because of the faster movement in QL and lower rail damage it is a lot easier to keep control once you have it. Bloodrun has changed in that you can now move between the yellows a lot faster and use the corridors and rocket fights to bring yourself back. T7 is a completely different story to the other 2 maps, it's about aim and positioning and you need to sacrifice a lot of items.
