I honestly find the heavy focus on melee across all its e-specs, and also core, to be the biggest turnoff.
Staff is available but it's a dreadfully slow, and boring, weapon. Scepter is just.. whatever, dagger is better. And now we've 1h sword across all specs.
I've mained staff ele (tempest & cata) for years now but I still get turned off by the forced "Battle Mage" class fantasy, yet I always come back to my ele.
'Tis a toxic relationship we share. 🫡
Also I didn't quite catch what game mode you've issues with, but honestly Celestial on Ele (pretty much all specs) work wonder in (almost) all GMs - I can't speak for PvP/WvW.
