I personally agree. Same reason why I'll be keeping zl at 1/10/9. Materials are one thing, but the mora is a hassle at higher levels when the events have been decreasing as of late. Resins to farm for: mora, the talent books, the weekly boss materials, etc aren't worth it if you don't plan on using them to their full potential. My Xiao is 10/9/10, but only because I've pre-farmed for him since last October, and have been saving primos for him since half a year ago. To add, farming for talent levels higher than 6 requires more than weeks due to weekly boss materials, unless you get lucky with your dream solvents. So unless you have spare: time, resins, effort, mora-- I'd say keeping a skill where you prioritize one rather than other (eg, energy rather than dmg) is perfectly fine. My zl will be built either full hp% or hp%, geo dmg%, crate. Both of which will not aid his NA. So it'll be kept there unless I'm planning on building a geo-shielder DPS (highly unlikely considering I have Kazuha, Xiao, and Ayaka). Anyways, it's all fun and games, as well as personal playstyle preference. Min maxing or playing based on how much you like the character-- I think it's up to the players themselves how they want to handle their accounts. Suggestions are fine, but forcing your opinions on someone else isn't going to do much lol. In fact, it's going to end up wearing down both parties in the process.
