Rough demo of how to do it after 3K patch as requested by rav. Wasn't concentrating this time and got cata killed, even forgot title. lol
Basically the idea is to agro the mobs near 1st boss spawn area to make a full block. Although I think this is too chancy if u don't at least have a good gun.
After clearing all mobs, leave cata in front of horse and it will slowly make its way towards the tent while all mercs go destroy spawner.
