if the xp rate was right why is it nobody can get past even 22k/h on the daily record when they clearly have a 6+hour log ontop of 24h slay lol, 25k is unreachable, and increasing it to that when you unlock dark beasts is just absurd, they lower xp rates if anything due to the fact you get like 12 for a task. 20k/h is reasonable if you get good tasks and power slay to max efficiency but that's rng due to the chance of just getting shit tasks over and over, so saying 180 hours out is pretty reasonable imho
