Hello there, and welcome back, I guess (although I haven't known you and started playing HC since October 2013)...
We have a new map called Haven... It's already full of towns...
We have the 'attribute' system... This adds more variability to gameplay and PvP... hc.to/attributes for more info
Several balance tweaks to classes... (Don't bother about questioning me about comparing classes from Dragongarde and now - I wasn't there then)
A new class - Shaman... not going too in-depth about this...
Towns have risen and fallen... (obviously, lol)
There's a lot more than what I mentioned... couldn't remember all of the changes so far...
If you're planning on hopping on anytime soon, I'm looking forward to it...
-Kenster1092, someone you don't know, but you might soon... lol
