Really?
Why are you changing the name of things haphazardly?Winter Gruoks/Grulets are now known as Palesnouts. (Treasure from them has been updated accordingly.) Palesnout Sows now appear where the Palesnout Younglings do to protect them.
Grass beetle change was bad enough where only one tier of beetle gets the name change so they stick out like a sore thumb. Both older and newer players don't find rhyme or reason for this. It's bad enough when someone asks where to find grass beetles and no one can answer them, new or old because they just don't know where the new beetles were moved and named to.
Know what could be changed instead?
Frost/Winter/Ice creatures.
Most confusing thing in Istaria!
T3 Beetles are snow
T4 beetles are frost
T5 beetles are ice
T2 Pygmy/ogres are frost (Ishkuk?)
T3 pygmy/ogres are ice
T4 pygmy/ogres are snow
T2 wolves are winter
T4 wolves are also winter
T5 wolves are yet another variation of winter.
I think. To this day, I really have a hard time figuring out what the name of the creature I need to be hunting for X tier.
