I think they should put equippable shields on the game
For example
A HEATshield charging it up one time would make explosive damage give half the damage and charging it twice would negate the enemies attack only IF it was an explosive attack

There should be at least 3 types of shields

Heat Shield
Energy Shield
Steel Shield

Think its a good idea?Well I think it is because it would make battles more

The game already has shields in, heat and energy shields to be exact. Energy depletes your energy to reduce damage, heat adds heat to your mech to reduce damage taken. Depending on the level of the shield you will block more damage at a higher cost to your energy or heat levels.
If you already knew this and you're looking to suggest something new, expand on it a little further
