I think the melodrama was necessary to build up the "who's going die" plotline. Fitz and Simmons planning a trip (strange timing for Simmons to be surfing the web), Daisy/Mac having a good cry, May confessing to Daisy, Lincoln quitting, etc. The whole Daisy withdrawal and Lincoln bit also gives some motivation for her being on the run six months later.
I'm glad Ward is off the show. His story was done.
Lincoln was the safe choice. Killing a minority or a female wouldn't have gone over well in the media.
I hope Yo-yo and Radcliffe join the cast next season. The former has some good chemistry with Mack (new partner to replace Daisy) and the latter gives the show a lot of levity.
