As a Cavs fan I must say I'm not very dissapointed with the effort so far but more surprised, I know the Warriors would be very hard to beat at home but there's a feel of invincibility in the air right now. If Durant plays like this no team would ever stop them really in the upcoming years and the NBA is gonna lose a lot of fans, just take a look at what these playoffs, completely pointless, all sweeps and no competition whatsoever. And we may even get that in the finals.
I still feel the Cavs can tie the series at home, but this will be a much harder effort than last year's. If they manage to do that, well I know the Warriors are a different team playing under pressure and the Cavs could have an edge there. Irving and JR will have to step up big time along with the some players in the bench (Korver and Williams). They have been atrocious so far.
Have faith on cavs. They can won a match on GSW, this is same scenario on last year. They are almost 3-1 then bounce back to win the championship. I agree with you that KD plays a big role now on GSW. He is the one who match up on scoring to LBJ, GSW will be having a hard time if they don't have KD. KD is closed to wear his first ring.

P.S.
-GSW can't sweep spurs if kawhi and parker is not injured.
I'm not a butthurt fan of SPURS!!
