Yup, that was me.
However, this change was done in good faith - goblins are usually found in GC, where they are unremarkable and rather weak monsters. I wanted to make goblin berserkers a bit more interesting. With their sub par Dex, they still cannot hit that often, but can at least occasionally damage the player now (in GC, that is). They also have rather low HP, so they die easily if you can hit them.
What I didn't know was that goblin berserkers will suddenly start to spawn in UT.
I have hardly ever seen a normal goblin there before! There, they are a bit hardcore, yes.
(Why are they spawning there? The weaker goblins are not!)
I still think berserkers work better now than before, because they are now a monster you have to take into account when playing instead of just squashing them. They are OK for GC, and even though they should not spawn in UT, they are still rather survivable there, with some planning, luck or use of resources (zap a wand, pray or throw items at them and they are not that bad).
Granted, I like my IVAN hardcore.
When they have +5 2H swords, that's just unfair, but I don't think that's on me.
