With your current hangar (at least what you wrote), My take on the order of using Storm Racks:
- Panther: This setup can be used past 10k+ SP. Even some 20k+ SP still use this setup.
- Killshot: Great for open maps doing hit and run tactics. But, Killshot is squishy. So, it is not viable at higher SP. A little warning though, if you go up against RuFFles while using this mech, he will chase you down! 😂
- Lancer: Situational depending on map at higher SP (6-8k range). Lower SP, you can use Lancer but, 16 energy limit really hinders this little guy.
- Guardian: Eh, some people are very pro Guardian. But, the mech is really squishy even having it maxed. It will work at lower SP.
Regardless of which mech you would like to use the SR on, the more important thing is to have a legendary reload implant for the SR ready. Otherwise, SR is very sub-par. Below are some links to YouTube Videos that might help you decide:
- Platinum LTA's YT video HERE. He explains how to setup your controls and strategy for maximum damage.
- Indiarium's YT video HERE . He talks about implants and also how to effectively use the SR.
- RuFFles's YT video HERE . He talks about what mechs (specifically F2P ones) that works well with SR.
Otherwise, do a quick search on YT for "Mech Arena Storm Racks." There are other great videos that showcases the weapon and mechs alongside other strategies from such content creators like (in no particular order) Kax, Omniverse, Mayer, BMP, and so on.
Hope this helps. Good luck and have fun! 🙂
