Some things can be, if they buff them up to compensate. As of right now its a downgrade as far as I can tell.
This is only an improvement if they buff us up to compensate, otherwise we're just worse at both since we can't specialize as much as we used to. Again as of right now its a pretty hefty nerf.namely ST/AoE mixed rows are in better shape
This also comes with the issue of us having to be balanced around being well rounded always, which is something that's likely to cause balance issues in the future. With the CDF change they removed one of the best ST knobs they had for the spec, and you're basically trading eradication for soul harvest which is a nerf to ST. It also really doesn't help that soul harvest is on a completely different CD than the other 2 cd's we potentially have. I'm alright with ST where it is on live, it'd become a problem if it goes down any more.
I'm just not super optimistic because they haven't touched anything in 2 builds. Maybe there'll be a big tuning pass later and this is still the mechanics and relative damage phase but I'm getting increasingly confused by the lack of anything in the two builds that they said would give us clarity.
