-TenZ +Yay and -Zombs +Ethan if possible, but in the real world won't happen.
I think TenZ is inconsistent with the operator on ct side (ascent+breeze), but I didn't watch haven. He is good with rifle though playing more passive with it and dashing in sides creating space. I think Yay is what Shaz and Sick are looking for in a Jett they can set him up on ct side and he will get more value out of the operator. Sentinels lost 6 rounds on ct side ascent and 8 on breeze. TenZ could and should make more of a difference if Sentinels wants be consistently winning. They can't depend on him when has a off or good day. Jett is a crucial role where you need to be consistent 90% of the time and have more "impact" frags then he do's now. For me Yay = the better complete Jett.
About Zombs he plays the shit roles on the team, but can get alot more frags if his aim mechanics were better. Adding Ethan will add alot of firepower. Dapr already plays a lurker/passive role so I think he might get used to controller role fast and can switch with Ethan if they want to play Omen. Also giving Ethan a sentinel role he can get added to the entry pack sometimes with Yay where he makes spaces and Ethan enters as 2nd or 3th. And he can lock down sites on CT where he mostly needs to focus just on his crosshair Instead of playing a controller or skye.
I don't see Sentinels winning, BUT they still can if TenZ pops off on the operator and gets impact frags it's gg.
