I'm so happy that DS9 was left to develop the way it did, though I do think some connection between VOY and TNG/DS9 would've been good.
There were of course all the rumours going round about a character from "Lower Decks" getting a part on VOY, and of course Ro Laren becoming a regular. There was also Sisko's friend who worked in the DMZ (whose name I cannot remember!) that they could have had in place of Chakotay.
