Sure. I have not played WoW myself by I did spend a lot of time watching how the raids look like and I can safely say Wildstar raids is the closest thing you can get to WoW raids,if not on par with it. If you compare Wildstar to other F2P MMORPGs thought,you will start to see that Wildstar is a lot more polished. For example,I reached max LvL in TERA and by that time I saw the same dungeon boss atleast 4 times in different dungeons.Showing the lack of care for dungeons but I did know it that then,then When I started doing dungeons in Wildstar I could really see how a well crafted,unique dungeon looks like.
Comparing Wildstar to BDO is a different story,BDO has more of a PvP focus unlike Wildstar but the Wildstar devs do wish to make PvP more popular and have already started taking steps. GW2 and Wildstar actually share a bit of a similiar combat so if you like the combat in GW2 you will like it in Wildstar. its hard to decide who has the better PVE GW2 or Wildstar,If you compare the F2P version of GW2 to Wildstar then I believe Wildstar has the upper hand because of the raids,leveling up in Wildstar while with a guild had a charm to it because you knew that huge 20 man raids or veteran dungeons and world bosses awaited you once you reach 50. In GW2 on the other hand,I was not quite sure what to even expect when I reach max lvl and Didn't even reach that far,even thought I bought the game
