I doubt it's cross class. I fish for a couple of hours everyday and almost every day I hop on miner or botany and spend a 1-3 hours doing that too. Rarely do I hit a wall. I don't mind the wall but I would like to see is a better focus on stats helping you 'target' the item you're aiming for (Ex: black sole, cobalt ore, mahogany logs, etc) so you're not just gathering forever only getting what you're aiming for 40% of the time. I like truth of mountains but abilities are so random it's nothing to count on, especially when it activates on your last gathering attempt.
