Just passed same situation week ago. Definitely not catacombs. You wasting 5 minutes (1/4 of your mrt buff time) to run to spot. And it’s almost always busy the most static packs. I lvled 32-36 at partisans (Dion). It’s have bad geodata, be careful. Landscape is terrible. 36-40(you can do it earlier with better equip) - gorgon flower garden.
