Isn't deck improvement part of the fun ?

I was looking to add some deck building game to my small board game collection and I am not really impulse buyer so I was looking and comparing bunch of options and at some point this game popped out in my YouTube, and it catched my attention because I love Lovecraft theme is 10/10 . Watched bunch of stuff about the game managed to stay mostly spoiler free just looked at revised core set first tutorial mission online to get the idea how game works. Went and purchased revised core set. But during this time while I was deciding if I want to try out this game I have read bunch of "starter decks are bad ditch them" " go online and find a better deck" And from my point of view this game is solo /co op game so I am not competing against anyone starter set campaign is pretty short and probably feels very similar on repeat playthroughs and seems like experimenting with the deck build will be primary thing to do but if I just go online and see what is meta build I will get robbed out of all the fun of playing campaign getting ideas how to improve my deck and trying them out on repeat playthroughs , it feels like buying disentanglement puzzle and just going to YouTube to see how it's solved before even trying . I come from PC games like torch light, path of exile, titan quest , where story is same or and quite often doesn't really matter and content on repeat playthrough stays the same but the most fun part is just iterating on your crappy first build getting ideas what can be improved and going again to test that build ... I understand that after some point with some amount of hours with the game it may be interesting to see what meta builds are discussing them and ect but recommending for complete beginners to just look up better builds online seems like robbing them out of 50% of what game has to offer
