What if there was a medium mech with a sword and shield that had a lot of fuel but has lower health than normal and has an ability that makes the sword to be more powerful and has a gain on speed. however in the ability the shield cannot be used. also the mech has unlimited dodge so it can get close enough without being torn to shreds making it evenly balanced as the mechs with guns can kill it but they just need to have a decent aim and there is so many counters for the melee mech such as the assault mech, raider, brawler and scout because of their dps, speed and armor they can easily counter the melee mech making the mech usable in the game without breaking the balance. in adition we can always report for nerfs.
How the weapons work:
the sword needs to recharge for 5 seconds and the shield has 500 health but the only way to recharge it is to pick up the cores left from dead mechs and needs a total of 5 cores to recharge unless a technician is with it. The sword has energy particles emitting from it when its usable and the shield is see through like the energy barricade. The ability lasts 15 seconds, the first ten is just to get to the enemy and the 5 should be enough to lower the health or kill it.
