I miss Exhibition Quests: three years have passed in JP since these last ones and I know that Lasengle is trying other forms of challenge quests tied to story progression, but I don’t think they match the feeling of tackling old school EQs.
I can agree with players arguing that the difficulty/reward ratio is not balanced for EQs (just 1 summon ticket?), but given the general lack of really challenging content in this game, I don’t think a few hard quests would overwhelm us: the only overwhelming factor was the timing, with EQs being available only during Lottery Events, literally the most busy time for FGO players.
Nevertheless, this video should prove that (with the right mindset) every player had a chance to have fun and clear the EQs: after all my servants are all either NP1 or NP2 (only Vlad being NP3), so finding one of them on support to SOLO these quests should have been doable even for newer accounts (though I agree that not having the right command codes can be quite a problem).
