In the new source, the spawn rates have changed in many maps. While some maps are now worse for training, it has also allowed for new training spots. Another change in the new source is the v0.40 maps for maple island. Most of these maps are bigger than in the old source. Some legacy quests like lucas' quest which gives a workglove and Biggs' quest which gives a fruit knife have now become available again which is great. However, due to the bigger maps, and the new spawning algorithm, the mob density has decreased significantly. Here is comparison of the EXP rates of the two most popular training maps. Note that dangerous forest hasn't changed in map layout. The difference here is purely based on the spawn rate. Old source: Hunting Ground Middle of the Forest II (aka pig map): 110k/h Dangerous Forest (aka mushrooms): 100k/h New source: Hunting Ground Middle of the Forest II (aka pig map): 65k/h Dangerous Forest (aka mushrooms): 50k/h We can't make a direct comparison, since the server's EXP multiplier has changed from 4x to 3.2x. If we multiply the EXP of the new source by 4 and divide it by 3.2 we get how much EXP this would be at 4x. For pigs, this is 4*65/3.2 = 81k For mushrooms, this is 4*50/3.2 = 63k This means it takes: 110/81 ≈ 35% longer to level at pigs compared to the old source 100/63 ≈ 60% longer to level at mushrooms compared to the old source I propose that the spawn rate is increased for these maps (preferable slime map as well. I don't have data for that, but the spawn rate is notably lower). I don't know by how much the spawn rates would have to be increased; I don't think a 35% spawn rate boost will result in a 35% exp rate boost, so some testing should be done to determine a suitable spawn rate. Another option would be to revert the maps back to the old source, however, as stated by Matt: and as seen in dangerous fores, the spawn rates will still be affected. Also reverting to the old maps will also mean that the new quests will no longer be available. I rounded the EXP rates for the sake of simplicity, the more accurate numbers for the old source are 111.5k/h for pigs, 99.7k for mushrooms. The accurate numbers for the new source are 64.2k for pigs and 49.1k for mushrooms. I rounded these up more because I'm not as familiar with the new patterns as I was with the old ones, so a small improvement is to be expected. I might even be able to get about 68k for pigs and 53k for mushrooms. However, since these are only marginal improvements, the point of this thread remains.
