It has been long this thought was brewing inside me 

What if legendary skins has some buffs 

Eg:  CROMACORE, SAWBLADE, POLAR BLUE For surge

insted of having them just esthetic let's assume they have specific buff individual 

Like CROMACORE has 5% extra speed 

SAWBLADE has 5% extra attack 

Polarblue has 5% extra ability duration 

Or it can be anything related to mech ability 

Like more stun distance, duration or various like additional implants 

This is will not only increase purpose to have skins but different ways to use them 

And for you mech arena new reason to sell them and minting more money
