Just raise the lvl cap to 100 and make a few tweaks to the skill perks, it can be done and would increase replayability
Skyrim doesn't. When you get a skill to 100 you can set it legendary and start again meaning you can gain levels indefinitely although most of the power comes from the trees and enemies do scale to your level as much as they can.Skyrim, Fallout, Borderlands, and just about every game that has a skill tree has a Lvl cap. Why should this game be any different?
Most of fun is in making builds and looking as they raise to power. In CP it happens way to quicker and way to absolute. If you want to be a netrunner you can bring legendary cyberdeck and hacks to Konpeki. It isn't supposed to be balanced for competitive play but just overall sanity check. Fix crafting/dismantling/upgrades quantities, quickhack damage/progression, more variance on cyberdecks and bit delayed cyberdeck progression or cyberdecks for non-main netrunner builds etc. or finetune cover penetration so tech weapons or buzzsaw can't shoot through mountain or concrete while LMG can't do plastic just like light pistol.its a single player game...
Even at hardest difficulty, at level 50, the game is easy as pie.
Had the same problem with TW3, had to download mods that made the game more challenging.
So in the current state of the game, that's the least of your problems, but I get where you're coming from.
Try to hit Sykrim´s level cap. You can play for 500-1500 hours before you hit it. Same with Path of Exile, Warframe etc.Skyrim, Fallout, Borderlands, and just about every game that has a skill tree has a Lvl cap. Why should this game be any different?
IMHO level should be acquired based on talent trees progression and those do take time - like you would need lots of anihilation exp to level up so using lots of shotguns or LMG, just like in Skyrim. Most talent trees level up super slowly after few of their levels. Like netrunner build leveling breach protocol, combat hacking, stealth and cold blood at the same time won't reach 20/20 prior to hitting level 50 even if using nearly only that combo from stealt. Needs some mob farming even. Also stats could be based on those trees. It's little sense you can pick high stat perks without level up the tree first.For example, you might have to invest 2, 3, 4, etc. skill points in order to advance further.
