I love Sazza, but rescuing her is kinda the 'big' sidequest for the goblin camp and completing it jumpstarts the grove siege, likely causing you to lose out on a lot of the rest of the content in the goblin camp.
Unfortunately yes. The issue is that even Minthara's very own introductory quest through Sazza takes away small yet meaningful dialogue to help us connect with the character and establish a proper backstory for the bad path.
Personally at the very minimum I'd expect from the bad path;
To have a more meaningful and lengthier introduction to Minthara in order to establish her as a long lasting character and become invested in her.
To captivate us with better and actual reasons on why the character would consider joining her, instead of just her outright accepting us and sending us on a raid.
Once the raid starts, to be able to do the same amount of interaction with the gobo raiding party as we can do with the entire Grove. Minthara's raiding party is nowhere physically on the map so there is no interacting with them, not even to make the invasion more immersive or interesting through minor decisions and actions.
To not have the Goblin Camp go hostile, but instead to become accepting to us and open up lore and story to provide some exclusive insight and backstory for the bad path from the actual NPCs.
To have some minor side-quests to do after the raid in the Goblin Camp. For example feeding Sazza to the spiders, torturing Liam, throwing rocks at Halsin as a bear or kicking the corpse in front of the gobo kids were good attempts at immersing us into the bad path.
To be as engaging and interesting as the Tiefling side, with potential future interactions from all of the NPCs in the camp or at least some of them.
To have an equal amount of content as the Druid's Grove so it doesn't feel like a rockslide when comparing the gains and losses between the two sides.
To gain Minthara as a romanceable full companion as compensation for Wyll leaving, with the possibility to save her from the Absolute and forever live with her in Menzoberanzan at the end of the story if she is chosen as the love interest. Or to forever condemn her into our own service.
To me this would be a start to make the bad path more captivating and interesting to experience, with meaningful content and outcomes, happening simultaneously with the Tiefling side during ACT I and then extending into ACT II. Because as many have pointed out, there's simply no competition when comparing the two sides in terms of content.
