From 3 day's i was playing only to find menagerist goblin and rainbow goblin. In this time i only find "1" pets goblin and 1 rainbow. My question is..what is the spown rate of this goblins? It's absurd to play 3 all day long and find only 1 goblin. I think tha dev's should make the spown rate a bit higher because it's so frustrating to search for them 1-2 day's in a row and find nothing. I think a lot's of players stop searching them because of this spown rate.
So far this season My group has ran into two of the managresist, and one rainbow. Add onto that an additional managreist that I found solo. On top of this we've also found 3 shrines, about 7 goblin packs, and had 3 portals open up. I'd say it seems about right in the terms of many of the goblins are actually spawning. I'd much rather have them be rare and make the drops something to achieve after I hit the skill cap wall so that I have something to keep me invested into the season.
I have found 3 menagerist goblins between the patch deployment and the start of the season, and only 1 during the season proper (plvl 580 as of yesterday). Meanwhile, the first rainbow goblin I personally found since 2.4.1 hit happened only two days ago (and it was during a TX public bounty run). C'est la vie.
I have found 3 Menagerist goblin since the patch dropped. We found one the night Season 6 started, and it got away because the noobs in my group weren't paying attention. I may have been screaming profanities at the monitor.
I've seen 3 (Got The Stomach, Haunting Hannah, and Blaze) so far, spawning at around 1 for every 10-15 goblins. I've also seen 3 rainbows. All on Torment 1. I'm on console, dunno if that effects goblin spawn chances, although I don't believe it does and I've been using this farm run to find them: https://www.youtube.com/watch?v=FjMiAGmLI3A
Got eight or nine goblins last night and one more pet. Up to four now! Truthfully I just run the bounties and then before leaving the map look and see if any of the common goblin zones are still open and run them before moving to the next map.
