TSM falling in worlds

So TSM just lost to MSF in stages and is out of worlds, this is just wrong, some huge changes need to be made,

1. to start off, I think Haunzer should leave, he isnt doing much except for feeding and once in a while he does a flash ult with gnar. In my opinion even Dyrus would be better.
2. Sven, in NA he ruled and dominated but fell in worlds like a car falling off a cliff. idk which jung can be better but in my opinon he is not in the level. What do you thing, what changes should be made in TSM after that, if at all.
