Loud fixed ban seems to be Fracture, and historically is a bad map for them, so it will likely be their first ban. It also might happen that they ban Abyss first because is their second ban, since Sentinels banned Fracture too and they will be forced to ban it instead of a potential Split ban, so Loud would have a "third" map ban, but i don't think they will play much with luck. Also they seem to have a decent Abyss so they might let it slide
On the Sen side, their first ban vs 100t was also Fracture, so it seems like not a good map for them; But with the tough map loss vs 100t, i think they might lose confidence and ban Split. Since it was their map pick i believe they might just have had an off day and still be confident on it, working on it for these past two weeks and even maybe changing the comp, but i don't know and i feel like they will just ban for now and work on it later (or at least not pick it first)
Considering that, i think Sen will pick Pearl, because it felt like a good map for them and they can antistrat the shit out of Loud, or Haven, which is more unlikely because it was their ban on first match (they might be expecting Loud to pick it instead). On Loud's side, i think it will either be Bind (Surprise pick that they haven't played + Lots of material on Sen) or Haven (Comfort pick + Sen may not be confortable on it), but im leaning more towards Bind. Decider depends on bans, but it might be either Lotus or Split, and im leaning more towards Lotus.
Pearl - Bind - Lotus
Feels like a 50/50 map pool. I think it will definitely go to Lotus and each team will at least take a map. With that map pool, im leaning towards a Loud 2-1 game, but it could honestly go any direction (specially with different pools)
