At current state though it has no major lacking side then the originals (except Demon/Elemental summoning and charlatan healers) but have many plus sides (revamped GUI, revamped and good automap, new NPC models far better then months ago and many fine tunings here and there) The game is expanding and will continue to do so. If you give it a try right now, I cannot tell you that you would not meet with any bugs(minor annoyances such as missing placeholders from texts etc), but I'd say they are not gamebreakers.
Hope this helps.
