I was not very open minded when i firstly played FFXIV when ARR was released.
That mindset did not allow me to play it for more than a month. Back then i was too hooked to WoW and i did not give any chance in other good MMOs as well for more than the first free month. But, because of the BFA disaster i firstly brunched out of WoW, for good, for the first time by playing single player games after so many years of either playing nothing at all or only playing WoW, even if i was not nowhere near as competitive in WoW as i did in the past, this was the only game that i was playing. Considering myself a gamer and not a "WoWer" that was a disgrace.
After i finished some very good games i had for so long in my Library, i said to myself lets play the second best MMO in the market, but with a new mindset now that i will not judge the game unless i reach the maximum level and content. I quickly realized that it might be impossible for me to reach Endgame because you should play all of the expansions in their fullest until you reach shadowbringers. I am not gonna lie, the ARR was slow and i pushed myself many times to play it, but afterwards each expansion was better and better. Especially, when i reached Stormblood i was so hooked with the story that i did not care about reaching the endgame at all.
From the get go it was bad for my mindset that FFXIV does not have PvP, and aspect of the MMOs industry that i really love it, plus the fact that i was nowhere near reaching endgame, i did not brute force my playthroughs and i was only playing for a few hours per week to experience the story. I managed to reach the end of Shadowbringers's first patch 7-8 months after my "first" start. As i said, the start was slow but as i was going i enjoyed it more and more. I was completely dried out when i finished the first patch of the Shadowbringers' story and i had already started GW2 which i liked it more but this is definitely a game that i will be coming back to check new classes, new iterations, new story, etc. I am currently having an active 6 month subscription (as i do with WoW) even though i am not playing, i do it because i enjoy it.
The take away for me was that you have to give a chance to a game for a few months in order to make a final conclusion whether you like it or not, nowadays i think that it is fine for any MMO to be completely different than WoW because they simply cannot win WoW in their own "game" and they should better do their own thing, back in the day all i wanted from a new MMO was -basically- a reskinned WoW, something that i realized it is absolutely pointless and of course impossible.
