How strong do I have to make my player to face stronger dinos

[Triggor]

Ok, so ive been wondering. So I know that with using nothing but your player (meaning no dinos, still using armor and weapons) what are you able to kill. Like I know a carno carno is pretty easy with 300 Hp and a small amount of melee damage with a pike and flak, but how much would you need to kill a trex with ease. And is it possible to kill a giga (Prolly not, but id like to know if its possible).
(And I dont want any answers for tek or range. I want to know if I can use some sort of melee weapon with flak or riot with boosted health and melee and kill a trex or giga)

With good flak and a good sword like mc or asc and 250 melee and 300 hp you will be able to kill a trex or even an alpha raptor 1v1 . 

If you sit on a good turtle you can use your sword to kill a giga but would have no chance on foot .

I know turtle can tank the bites but won't it die from gnashed long before you get to hurt it too much?
