I’m pretty sure it can do both! The games are bound to have to shared elements, it’s worth discussing.
Anyway, I think Wonderlands should improve the skill system in general. It’s been an issue since BL1, but builds boil down to correct answers rather than diverse playstyles. Especially in BL3 where feedback on builds is “your build is not good enough for m11” etc etc. It’s partly a fault of the health bloat, but I’d like the focus to be on skill synergies than raw stats. Sure there should be ways to make the best version of that build, but I just want more choices. Let us get creative! Health increases are a part of difficulty, but absurdly high health values do not encourage build diversity.
Give us more effective ways to build our character too. If there’s a pet-based class, give us ways to upgrade their damage outside of skills! If Gearbox could stray from their classic skill system to remedy this, that would be really interesting. It’d even separate itself further from mainline BL games.
