This is the best version yet, just updated from 4.3.8 to 4.4.3 on my dedicated server. The players have reported marginal increased FPS, virtually no lag and forges seem much better. The visual effects look really nice too. I like the new class system, it forces you to play out the quests and multi-skilling is a must. The implementation of some A16 ideas is so cool. Well done.
PS. Is there a text explaining the class system somewhere? It is like the blind leading the blind running into it for the first time, everyone is in the dark.
