A great big break frrom love triangles would be a good start. Let some happy couples exist for a while.
Write for the characters, respect their history. No more WTF moments, please. I got so tired of thinking that so-and-so would never have done that. And this applies to almost everybody - from Viki to Jess and Nash, Natalie, Dorian, Clint, Marty (she's on my ugh list, but still, Marty would never have married Miles).
Tidy up all the loose ends. Who killed Spencer, who is Paige's real son, and is Tommy really Todd's child? This should have been done months ago, but better late than never. Make David the Buchanan, and do it fast.
