The worst part is the wait in between. Find a group in set blocks. I recommend west side ledge by the mag. Use crispy meats. Have your mag and food buff active. The boss here moves a bit but it’s much better than the sword boss and it’s junk ass hitboxes.
Do not go in below 20. Nobody will want you there. You’re at a major disservice to yourself as you won’t do any damage, you may get no loot and everyone will ask you to leave. Typically politely but regardless.
Gigantics need a tab similar to rank 2. The open regions need a level 20 only tab to avoid generally normal players for having to leave zones they may just be farming in on there own. When you get around people make sure everyone is 20. Most people by now know this already and won’t be less than 20. If you see 18s/19s and nobody even mentioning it, get to a different block. Immediately. You’ll be wasting time for the enemy and wasting time for a kill that won’t be happening.
