Atm it is really hard to get crushed bird nests for ironman as there are only 3 methods of obtaining them:
1. from wcing but this is really slow (think I have recieved like 20-30 nests in 150m wcing xp)
2. Kiling callisto who has a chance of 3.15% of dropping 75 of them
3. trading in 20(!) mole skins or 10(!) mole claws for 1 bird nest
These methods are all really slow and the only one that is decently fast (callisto) is purely based on luck. Hardcore ironman won't even be able to do this method as it is way to deep in the wilderness.
What I wan't to suggest is that trading mole skins/claws for birds nests should go to 1 for 1(just like osrs), this would make it way better for ironman to recieve birds nests. If this would result in some kind of seed being to easy to obtain, make it so that the bird nests are already crushed or empty, so it can't be abused for high level seeds.
What do you guys think?
