Think her issue isnt the fact shes done with old content.
Her issue is the game has no current content built for the solo player.
WoW solo content has only ever gone as far as a Rep grind, or some borrowed power system really, and sure endlessly collecting mounts and achievement points is something to do but it aint exactly a florishing end game
Honestly. Id recommend any solo minded player. Who dont want groups, guilds, forced into premade content and simply want to engage with the game and get rewarded for it in all content. To play gw2.
WoW GW2 and FFXIV have their corners of what they do and dont.
GW2 and FFXIV ironcislly both have the same downfall, their raiding and gear progressive options are limited.
WoW has a easy win by ruling this niche effectively, WoWs popularity would fall immensely if blizzard did what this thread is asking and we all know it.
WoW cannot compete with ffxivs story telling. Its too far behind in systems to catch up to what ffxiv offwes these players. Between the housing systems, the RP side of things, and also the casino place that always is packed with players.
WoW doesnt have the set up to make open world as large scale as GW2 doesz the games server would ignite trying and phasing will always make it feel alot worse then GW2 in that sort of design.
When i wasnt wanting to raidz i quit WoW i just returned rly as my lifes calmed down more for me to make the comitment to raiding.
These other 2 games would quite litterally end WoW in a month if it started trying to compete against them
Same as when gw2 launched raid content it flopped, and when they dropped strikes it flopped alittle less but no one rly does it.
People dont play gw2 for raid content so it half killed the game when they tried pushing it.
