First of all, thank you for approaching the community very open.
Broadly speaking, I would say a skip is ok. It would however need to include:
1 or more pre-leveled warframes
a couple of pre-leveled weapons
builds with pre-leveled mods (should be installed) for the gear
That being said, I enjoyed the quests of warframe a lot and would encourage the skip to still give an incentive for players who used to go back and experience the old stuff.
What the skip should absolutely not contain:
cosmetics
exclusive stuff
