disagree, SEN's map pool is not as good as G2s.
G2 doesn't have a "weak" map, aka a perma-ban. They've banned whatever they felt like, and I think we saw them on all 7 maps in the cycle, and none of them looked particularly weak. Haven was their worst defeat by far (against C9), and then they smashed 100T and took it close against MIBR, so it's not weak either.
SEN hasn't looked particularly strong on any map, and they do have a perma-ban, fracture. Their match against MIBR isn't a good demonstration, as Aspas was on a bad day, then popped off against G2.
So SEN lose Split, Fracture, probably, assume they ban it.
That leaves Lotus, which is an easy win for G2, despite the ridiculous copium that sen fans are putting here (which i cannot believe - G2 have looked nearly perfect on it, and they only lost to EG, with a crazy clove comp and yay popping off - not happening with SEN, as they don't have yay).
Haven hasn't looked amazing from SEN either (if you watch the vods, not the scorelines) - not good for G2 either, I'll give it a 50/50.
Icebox is a 50/50, SEN took it 13-11 which is a close map last time they played.
Ascent is a 50/50, another close map, though I think G2 got better on it (they played against the SEN comp by MIBR yesterday, destroyed it).
The other map is Pearl, G2 always manage to make it to a 2-round difference there, so I don't think SEN will win (literally G2 needs to stop my heart attacks please) there either, but i'll say 50/50.
Clearly, G2 has the better map pool - 3 wins, 4 50/50s is way better than sen.
