First, a huge THANK YOU to OOO for fixing the keyboard facing bug I reported here! THANK YOU THANK YOU THANK YOU! I can't tell you how nice it was to be able to aim again, can't wait for the change to be implemented in-game.

Gorgos: I'm digging the new baddies. Aesthetically they are different enough to be unique, but still walk that menacing/adorable line that players have come to expect from the game. Also, their movement patterns and attack pattern is a nice departure from the rest of the fiend family--I liked that we didn't have another ranged attack to contend with, but that the combination of their being able to quickly close distance, along with being particularly aggressive, still made them formidable. Glacies mentioned that they could do with a bit of a health buff, and I would have to agree on that point: not only do you have a certain expectation of their having higher health based on the look of the baddie, but they are also the only fiend (minus silks) without the aforementioned ranged attack, and if they are going to get up in my face to attack I expect them to require more hits to take down.
A few things I noticed: first, am I correct that the number of bites scales up by tier? I could be wrong, but it seemed like I was getting 1 bite-3 bites, by tier (will go back and recheck this). Second, and a related problem, the second bite in t2 kept missing me. At one point I just stood still to check the damage, and every time after the attack telegraph, I would be hit by the first bite and missed by the second. Most of the grogos I ran into in t3 were in the arenas, so it was a bit harder to see if the second bite connected with all the damage flying around. Still, it's worth a look to see if the second bite isn't connecting with the players. Third, damage-wise they seemed to be in-line with the rest of the fiend family, but drop-wise they seemed a little light compared to devilites (and especially if their health is buffed a bit). Again, hard to be certain as most of them were in arenas where it was more difficult to keep track of numbers, but as long as they are similarly in-line with devilities I think the drop rate will be fair.

Fiends: As with most players, I do not look forward to encountering a swarm of grievers, and there were noticeably fewer of them in the levels I ran. I would say that overall, I felt the difficulty of the levels was more consistent with what I expect from the other enemy families--i.e., "easier" with the changes, yes, but still on par with other regular t3 content. Some people will complain that this is another nerf to some of the hardest t3 enemies, but I think the more balanced difficulty level will ultimately provide more room to expand into future content.

One final note: again, might just be me, but baddies overall felt more aggressive. Zoms, in particular, are kind of notorious for getting hung up on each other and ignoring players, but I had two of them legitimately FOLLOW me from room to room as I raced through trying to find gorgos. I don't know if any changes were intentionally made to overall enemy behavior outside of the addition of the gorgos, but regardless, whatever else was changed seems to have had some effect on how other enemies aggro to players (in a good way).
