Solid lineup, hard to argue against any of the players.
Similar to Pasch's but this is probably stronger so long as Void and Saya can understand Mowz's calls.

I can come up 3 rosters in about 15/20 mins...

eng speaking:
-Tanks: ChrisTfer, sharyk
So many good tanks, could easily choose Fct or Tonic (even Kaiser). Went with chris and sharyk based on old synergy with team uk and eunited.
-Flex: Smex, Gods, uNFixed
-Supports: Adam, Roolf, Wins
Flex supports are the hardest to fill imo. Wins is as much a coach as a player. If i could think of another tier 1 Ana/zen I would put them in over one of the flex/dps players (probably smex). That way you could do in-house scrims.
-DPS: aKm, Davin, Kruise, Vallutaja
aKm, Gods and uNFixed can all flex on dps. Davin and Val for tracer and Kruise for Genji (Kruise over Kyb or any other genji Bc of synergy and potential lucio for in-house scrims)

chn speaking:
the MY roster (with extras but I haven't followed any team outside of MY in China enough to know who)

kr speaking:
Runaway (obv - Haksal due to age) with a few additions from Meta Athena, RX Foxes and LW red

Edit: Just read the rules again and Runaway are banned because they are too obvious (and op)!
