Yes the whole process of doing tasks is just waste... just selecting by voting is the main problem in the format.. format is unfair.. if it s not voting then deserved contestants might be in finals.. just we can know how the contestants is playing and their mindset through the voting process.. that's all..
I agree, I have seen almost all American survivor and right now started Australian Survivor too . And yes any one good at tasks never last in this game. But if you are good at being friendly or trust worthy and have an alliance strong then you can win it.
