For sake of this post Sen will be team b and heretics team a
Th ban 1: ascent, its their perma ban. No reason to not keep banning it. Unless they have something crazy, I think Sen are still better on ascent than them a W, so ascent banned. Honestly great for Sen they can save a map ban.
Sen ban 1: really th’s pool is like lotus bind sunset abyss, but after that drx game on abyss, I doubt th feel great about it compared to the rest. I think optimal map ban here is getting rid of bind, heretics is pretty good on it and I don’t think Sen is as good as heretics on it.
Th pick 1: really down to sunset or lotus here, but I think they take sunset. So far been a dominant map for them, and Sen have looked shaky at times on it in these past few matches.
Sen pick: this should be an easy haven grab, they look great on it and heretics don't, simple as that.
Th ban 2: down to icebox, lotus, abyss
I think heretics likes lotus, and so does Sen so probably won’t ban this. I think icebox was ok for heretics, and same for Sen. Abyss for heretics seems mid and out of pure doubt of what Sen play, heretics ban abyss.
Sen ban 2: ok Th looks strong on lotus. Only dropped the map to lev. Knowing Sen, I think with the amount of footage they have on heretics lotus(even though Sen has a lot of footage), they will try and antistrat this map the hardest. They ban icebox.
Map 3: lotus
In summary,
Map 1: sunset
Map 2: haven
Map 3: lotus
