This might be a bump, but just in case it hasn't been covered...
Why does the Incin's heat siphon not have any visual to it besides the little indicator on the HUD under the health bar? I feel like an in-game visual feedback would be SUPER helpful to people understanding the mech/mechanic better, as well as introducing it to new players more effectively. A lot of people new to this game don't even recognize that this game mechanic even exists, and furthermore, it's really helpful to (new) players who are more keen to use sustained-dmg weapons as well.
Something visual along the lines of the Heat-Charge item's animation, but maybe a different color (like blue instead of red) and have the waves move in the opposite direction, towards the center of the animation's sphere (towards the Incin). I get there are a lot of issues with this suggestion, like the animation clipping through walls around the Incin using it, as well as the memory cost of having this animation run constantly, because, like, Incin == spam... Just an initial thought thought in terms of designing a better visual feedback loop for the player to get a feel of this functionality in the game.
