Overheat!

There is a discussion these days about how hard is the difficulty of Shadow Lairs talking about tier 4 that brought up another subject the 6star gear.
An idea came to mind to find an alternative way to have stronger weapons without having 6 star gear.
Shadow lair is basically endgame,An endgame player pretty much has all the gear he needs,although he keeps playing the heat is useless unless he constantly tries to craft new gear for collection reasons.So I thought why not create an item that could store the heat(imagine it like a battery).It will be an item that you need to alchemize,the materials could be some enamorocks that could give some more meaning to the krogmo awards.That item could be equipped as a trinket.
How it will work.Imagine that this battery item when you equip it,it can store heat from playing in depths/missions.
When the battery is full and when you are in Shadow lair Lobby you can activate from your inventory.The Battery will overheat your first 2 weapons and stregthen em enough to do enough dmg for the monsters of SL.If you have 4 weapons you need to have 2 batteries and the second battery will stregthen the other 2 weapons that you might have.The overheat will be for the limited time of doing the Shadowlair and it will give a slight aura/glow to you weapons.
Why do this?It will give more importance to heat,motivate players to pvp for enamorocks,motivate people to buy more trinket slots and balance a bit the shadow lair.Futhermore it is an alternative choice if the 6 star or shadow lair gear plan is harder to make them.Should it exist in other stages outside the shadowlair?I think it will mess even more the already problem that we have in the balance of the gear.Maybe outside the SL the duration will be less for a minute?But then it messes with sprite bonuses and stage bonuses again..
I know that it might not sound as exciting as getting 6 star gear but I think it will be a nice add without messing more with the balance of the gear..It is just a suggestion feel free to add ideas,to like it or not,just in a polite manner please.When I was new to forums even if my idea might was silly some people were very agressive in their posts making me not wanting to post anything in the forums,I felt forums it was a closed club or something.I do not care much nowdays but I just saying that when I was new it was not so pleasant.

I think most of the problem is that players aren't willing to go beyond acheron, because the game gives incentive to stick to one or two loadouts and buff them with UVs rather than branching out. In essence you're suggesting that players be allowed to further disregard the variety of gear set out for them in favor of super-duper acheron.
The other half of the issue is that enemies do 1.5x damage ish. This is an issue because you basically have about 2 hits on you at any given time, and you really can't afford to give up your damage bonus in T4, since it takes a while to kill with it anyway and lag etc. will sink in after a while due to online play. Overall I'd recommend an armor balancing update that ends with everything on the stronger side.
I'd personally like just allowing us to keep heating gear after level 10 to let it incrementally become more powerful. Gear will still be limited to dealing its normal damage per tier as it currently sits, but 5* gear can be leveled up might higher to allow it to be competitive in shadow lairs. Regular clockworks and PvP would keep current values since those depths are set, but in shadow lairs the depths are deeper so they can allow better scaling.
This would allow players to always keep working on their favorite gear and be able to tackle shadow lairs without imbalancing the rest of the game, but also keep their progress permanent - you're already paying for a key, you shouldn't have to pay to also use your gear at its max potential.
