Here are my list of players who I think will have a big jump in improvement in VCT (top three per region) - no particular order
Americas
- zekken
- mwzera
- Shyy
EMEA
- nAts
- Cloud
- qRaxs
Pacific
- invy
- k1Ng
- Dep
Most of the one you mentioned already had a great last season, except shyy, mw and qRaxs. These 3 had decent overall. Of the ones you mentioned i think the ones that are more likely to keep that are zekken, who just added a better igl, nats, who is in a region full of new inexperienced young players, and a top of the table team, cloud who just added a good igl, and a great replacement for rhyme. qRaxs got a team for top 3 emea so he can get to a better place but lets remind hes a support player so its not his role to frag out, and the same argument you can make with mwzera, but who knows what role hes gonna take(he played viper, flash initiators, sova, raze last season). Shyy should have a better season as he is gonna have more flexibility from onur style, and i agree on him having a better year.
My picks are:
NA-shyy-qck-oxy
EMEA- runneR-yetujey-takas
APAC-iZu-Jemkin-Monyet
