If there ever will be a Baldurs Gate or a Faerun Lore like MMORPG with the engine of GW2 or TESO then count me in. WoW + Neverwinter Online is pure eye cancer... + Neverwinter has shitty or no translations...
Guild Wars 2 is such an old engine they do not even support Direct X 11. It has massive PvP battles ok.
WOW updated into Direct X 11 graphics really long time ago even when I still played it.
As for massive PvP battles I find the upcoming DnD MMO more interesting (I do not know if it will have massive PvP battles that is unknown) but it is certainly has the possibility with its brand new Unreal 5 Engine.
From what I have understood Unreal 5 engine is better graphics then Unreal 4 but not only that better suitable for massive battles at least that is what I believe.
Well and the upcoming MMO Ashes of Creation (note Ashes of Creation is fantasy, but not Dungeons&Dragons) is the new KING in massive PvP battles. Its aim is up to 500 vs 500 players while not yet shown that it has already have larger PvP battles in Alpha then any Guild Wars 2 PvP battle. Ashes of Creation will use Unreal 5 Engine but be warned system requirements can be high for massive PvP battles.
