I find high-level Nikke pretty fun but it's definitely not for everyone. There are some advanced mechanics to learn like i-framing and quickscoping but the latter can get extremely tiring to do for a long period of time.
Certain mob patterns are an extreme pain in the ass to get through and bosses can do a shitton of damage so it can get frustrating.
Stat penalties are quite severe at 30%+ deficits so team-building and gearing becomes very important too.
You can always play it as a side game and farm resources until you can blow thru content. Watch YouTube for later chapter stories if you don't feel like waiting.
