Is this worth it

[LORD CHAOS]

Guys i still haven't done it and i need some advice 

Do you think that using these useless PREMIUMS is ok 

[Stevelord]

yes it is okay make it mythical 

[noㅤ]

It depends on your build but every item you're about to use is less common to get than the Rock Recoiler so personally I'd upgrade heat and energy modules to legendary and use those instead.

Well, I do not see useless parts there depending on current rank. The rank and power use can variate the use of a part in some different combinations. 

For example, the stone leg, it is a need part. If you do not have one, then do not eat. The claw it is a good part too and can help depending on the use. If you do not have one, save that one because might have hard time to get one back been premium. The roller it is mid rank and can be use as meat having a claw and stone feet, The runner it is a premium part to be use with some configurations and should save one. The supreme cannon can help to reach R5. 

Just be careful eating parts or will lose your golden eggs

i wouldn't use the sparked runners, rolling beasts, the claw or the massive stone feet they can all be used in some op builds.
