Of course having Saskia and/or Iorveth in the game would have been nice, but only a very limited amount of players would have ever met them.
Couldn't that have been said about Roche and Ves? Why include them?
The point is, it wouldn't have mattered if you included EVERYONE from TW2. Roche and Ves still live in Iorveths' path and Iorveth and Saskia are still alive on Roche's path. EVERYONE that plays TW3 would be able to meet them.
The only characters that would be harder to implement into the main story, but easily as side quests would be: Dethmold, Stennis, Siegfried, and Aryan.
CDPR dropped the ball on this is the biggest way possible.
Roche survives regardless of choices, if I remember correctly and he also stays somewhat of your ally either way, while Iorveth stays your enemy, if you side with Roche.
Saskia can actually die in both paths, if I remember correctly, since you can slay her at the end.
This is so disappointing. They literally just ignored half of the TW2, giving the people who sided with Iorveth/Saskia absolutely nothing.
