All this thread shows is that a lot of people don't understand game mechanics.

Legs which only have 2 uses are at a huge disadvantage compared to normal legs so of course they need large damage, heat damage/energy damage and HP buffs.

Imagine you use your legs twice in a fight (and that often happens in a long fight, especially if someone always attacks next to you with a sword) and then they move next to you and you have no sword or shotgun, or you have an energy using sword and your energy is drained. You simply cannot move or attack, and because the legs have no jumping capability, you are stuck next to them and at their mercy. And if you have a mythical sword with 4 uses that can also run out, leaving you with no weapons to attack.

And having a lot of heat damage on your legs isn't going to make a huge difference if your opponent has a lot of cooling, so these legs aren't something you can rely on alone. Or you'll use them twice, your opponent cools down and then you're extremely vulnerable if they get close to you.

They are good legs, don't get me wrong, but you have to use them with the right strategy and they don't strike me as unbalanced compared to other mythical legs.

A weapon I do consider slightly unbalanced and overpowered is the infernal axe, the only melee weapon which doesn't require any energy to use, does huge damage, heat damage and quickly drains your heat capacity. When people use it with a high heat setup and combine it with the lava spray, it is basically a winning strategy (as has been shown) and there are few reliable ways to counter it. The 4 use limit on it is a downside but most mechs are basically dead before they can tank a full 4 hits and hits from the lava spray.

A big rebalance on rocket weapons has to be done again to make them viable. At some point rocket strategies made sense but now most heat weapons which don't use weapons are almost equivalent and save on storage space and don't run out of ammo.

The devs need to look into rebalancing rocket weapons.

Also I fail to see the point behind the heat eruptor drone. It does the same damage as the other heat drone but uses bullets, and neither one use energy. The fact that it does 4 max heat damage seems pretty inconsequential if you need to use bullet modules and can run out of bullets (after which the drone cannot attack.)

Other weapons need and drones need rebalancing too, like the "breaker" and "discharger" top weapons. They are useless compared to other top weapons like orbs and novas, and nobody uses them because of their lack of uses. Okay, the engine breaker is sorta possible to use but still not really worth it.

Just my two cents. The mythical shop is pretty unbalanced, but not in the way many people on this thread claimed.
