for people not invested in ozfortress this roster is ridiculously stacked.
If you were (and people will inevitably) compare them to Jasmine they are potentially a much more solid roster. In terms of scout combo, roamer and medic I'd argue straight upgrades. down and lau are about as scary a combo of scouts can be; lau is plain and simple the best aimer I've seen in TF2 period. lock is individually one of the smartest and most mechanically skilled people I've ever played with. rky is unfair, he's like an anime character I don't get how but his power just scales to always be on another level of the people surrounding him, Australia hasn't got a reputation for fantastic roamers but rky has broken that curse.
In terms of demo and pocket you couldn't find better replacements for geoh and Paulsen then with hertz and enrith, enrith is the only person who could contend with Paulsen for his strengths in maincalling and aggressive strategy, and whereas geoh had some of the best aim and dm in the country hertz is a super selfless player who's mindset lies solely in what his play can do to make his team's job easier.
