A few things I would like to see changed for MCH making it less ping-punishing and a few other changes.
Hypercharge: Now grants 5 bullets instead of a timer.
Heat Blast: Now uses the bullets from Hypercharge. Instead of reducing cooldowns, it instead gives Aether Charged Ammunition at a rate of 1:1.
The Aether Charged Ammunition can be used for a free Gauss Round/Ricochet.
This change would mean you no longer have to weave inbetween each heat blast, but can still do it if you want to.
Wildfire: Duration 15 seconds, explodes after being hit 6 times, now does AoE damage.
Gives you more time to fully proc Wildfire and also makes it usefull during mob pulls in dungeons.
Crowned Collider: Gone. When the Automaton Queen uses Pile Bunker it grants the MCH the Targer Locked status. This lets the MCH use the Marksman's Spite attack (similar to the PVP LB).
As it is now, Crowned is the MCH's strongest attack bar Wilfire. But it's something that is done very passively by the mech. This change would instead let the MCH get the visual effect of the attack.
Flamethrower: Share cooldown with Hot Shot, grants battery, same AoE as Bioblaster and applies a DoT. Hitting a target affected by Bioblaster causes an extra explosion to trigger for additional damage.
