Have you not seen the Eastern wilderness slayer areas? Tons of aggressive npc's to train at even without training slayer. Both "forts" have NPC's upstairs and downstairs as well. If you combine that with the rest of the wilderness and all of the training spots outside the wilderness there is definitely no shortage of quality training spots.

yes thats where i've been training all week on the eastern part of wilderness and its been packed. hence this thread. other spots are usually packed aswell.

another suggestion highscores for tourneys,survival,hunger games and on the flipside highscores for who donates for events the most to have a little friendly competition for something that benefits the server

This here is a great idea imo ^

And a few more npcs for training spots doesn't hurt +1

Maybe look into non afk training methods like slayer for more variety in training.
