Here is a chart from Monkly Business that shows regen rate for Iksars (and thus for Trolls):

As you can see, the regen rates for Trolls here are waaay higher than on live. They start at 4 standing and 6 sitting here, while the chart indicates they were supposed to be at 2 standing all the way up to 50.
What do trolls get at 20 and 50 here?
