Dimma damn that's a good idea. I barely even touch the reroll system in its current state and just try to make long chains. Nothing else, no thought to what it is on the board except for the rare nodes like strongboxes or exp at the end of the chain if possible.
Yeah sadly same. Unless (and I haven't tested this) each node has specific chest that it can spawn it doesn't seem worth to take the time to 'setup' the board other then the beginning and end.
thats a really great idea and seems super obvious thing to add when you think about it :o , but how ggg handles everything nowdays they will probly just buff the drops by 10% and call it a day
