five teams in DOTA are unanimously considered S-tier at the moment (in order of strength): Secret, VP/Liquid, EG/PSG.LGD.
In the three matches where S-teams are facing lower competition, odds are currently:
EG -161 vs VG
PSG.LGD -204 vs NiP
VP -435 vs Mineski
I think that NiP is a better team than VG and that PSG.LGD is a worse team than EG, my instincts say that NiP is the value side here. PSG.LGD has only been crushing cans as of late. I love my Chinese teams, but they are obviously in a rebuilding state right now and being the top dog in China right now doesn't say an awful lot. (sorry for mixing up the formats, but I like American odds better when eyeballing risk and decimal odds better when accounting)
.75u NiP @ 2.63
1.5u NiP +1.5 @ 1.52
EDIT: justifying my EHOME action above, I'm banking on North American DOTA disappointing as they pretty much always do. I know that EHOME is missing a player, but I just can't trust NA teams as favorites. They are almost Brazil-tier.
