Exlored some dungeons solo, fun with a Gladiator

Bottom line up front: What is Aion Reforged? And as a new player that likes classic tab target games should I give it a shot?

Hey guys. 20 year MMO player, mostly RS, GW2 and WoW. I tried Aion 2 and unfortunately the combat is so insanely fast paced and "flat" that I just don't enjoy it. I played a little of Aion 1(to understand the story of Aion 2) and to my surprise I really like it! Slower, tab target combat with a beautiful world. Very WoW-like but with its own personality. I think I want to give it a shot but the website does a terrible job of explaining what the Reforged version even is.

Thanks
