There are differences between them like you said as HP. Now, you have to take in consideration the weight between them. Nightmare will allow you use more weapons or better module set up. Do not spend in things you are not sure. Just think. Don't do what I said. Do what do you think will be best for you and your preferences that you might like. Nothing is perfect. Just pick desire type of mechs or combos. The important is to think before eating and do dummy movements harming the account progress. Also, when we start, it is hard to have the right things and we use what we have to keep moving on.

Ok I will upgrade nightmare and replace flame battery and nightmare is cheap so it's gonna be easy to get it at legendary, thanks for the tips And also right now I upgraded nightmare to epic and it doesn't give much HP but we can't say it's still an epic when I get it to legendary I will upgrade and compare bothnflame battery and nightmare

we do not know when will get a desire part. As an example for me, I was unable to get a Windigo in the freeway until I spend some tokens from savings them during free development and that included had to buy with free tokens the old offers for old modules deal of 500 tokens to get them. It can pass a year or more and no luck. All accounts work differently. Luck it is different. Basic is farm a lot and get luck farming to get the part. The other option is to farm a lot and enhance a factory until reach the EPIC craft area for possible drop, but it is expensive. The other option, it is to save the tokens earned until now and beyond to get a decent offer. You can ask about it. Max this until reach EPIC level 30 all of them. Will need transformation but have to happen Farm a lot to get that locked space. Focus in your primary mech all best parts. Do not share them for now. Best to your best possible mech. You can get Nightmare easy. Just farm. Do not use the other torsos. Just focus in your first mech. You can l40 the torso if need in "Flame Battery" been at Legend status but not more than L40 for now. In the sideline go for Nightmare if no other torso appear. You can make 2 of this. Are good for heat mechs and physical mechs. Can work for energy but it is less good. If you will go for energy and nothing else is good, you can use the same torso energy version if have too to go for. Just show your progress time to time and careful making parts or eating parts.

OKI DOKI I appreciate you typing all that, I'll try to get windigo and use that torso instead of falme battery and I'll try to get epics so I can upgrade my massive stone Feet since your saying their the best I am grinder story and tokens for the crates and hopefully get good stuff I also may upgrade nightmare since I see a lot of ppl using nightmare and saying it's good

do not eat those 2 legendary parts next to the frantic. the heat work for pvp but important for raid. The energy one is important for energy mechs for some configurations and sometimes it is hard to get. Make legends with epics that won't be needed. you can ask. preserve some epics that are important for the future. Manage properly the inventory.

Thanks for the help, I finished the special quest

anyone can help here?
