I am genuinely curious, did you try building your own character or did you solely used build guides?
For me personally creating my own builds, regardless of how objectively good they are is the most fun and statisfying thing about any kind of complex game like LE.
Getting a somewhat decent build running on your own is really not hard and I always feel like a lot of people are too biased or afraid, because of other games to even give it a try.
Also a lot of builds out there are simply not fun and good for certain types of players, so maybe you just have not found stuff yet, that you would really enjoy.
Endgame feeling boring is something a lot of people brought up, even though I don’t think this way.
Leveling feeling lackluster is something that I don’t udnerstand as well, what exactly is lackluster?
I feel LE’s leveling experience is one of the best of it’s genres, simply because your character can develop into an actual thought out build very fast. The pace of progression is amazing, nto too slow, but also not overwhelming or daunting.
I don’t want to de-rail this into some off-topic with speakign too much about other games, but I feel like Lost Ark’s leveling experience is waaay inferior to LE.
On the endgame side I cant compare it, but I guess both games are hard to comapre anyway to begin with.
