Velious and exp penalties question

[Eumora]

I have spent the last 1-2 hours searching this forum for information on the experience penalties inherent in certain classes and races. I saw in a post that the penalties(or at least some of them) were going away with the release of velious, but I haven't been able to find any kind of official post stating that that actually happened. Every post I see from it is years old(newest one was from summer 2015), and I can't find any release notes for velious(hell I can't even find anything confirming that velious actually WAS released). Searching on this forum is almost useless it seems.

In light of that, my question is: Did the penalties go away, and if so, which ones? Better yet, what are the current penalties and bonuses in relation to classes and races? I am about to make a fresh toon so I need this information. As is the case with many people, I work a lot of hours, and simply don't have the time to level a troll SK if the penalties are still in full swing from classic. If such a post exists, I would appreciate a link to one detailing the penalties(or lackthereof), and whatever changes were made(if any) with the release of velious. Thank you.
