It is not a news flash and no need to be aggressive over this topic. Not to mention I am not talking about making all jobs simple. I am talking about just keeping the MCH the way it is and just expand on it since it is in the right spot in my opinion. The other jobs is not the main concern of my previous post.
People experience with a job varies and there are still people who find jobs easier or difficult to play but mostly due to how they prefer their play style. While certain players may find all jobs easy to play no matter what, there are others who do find certain jobs more difficult to adjust to playing. Some people prefer the more simple play style while others may perfer a more mechanically focused play style. You may not find this surprising or do but there are people who even find MCH to be the more difficult job to play as simply because it is too simple as their minds and muscle memory are far too adjusted to Jobs like Monk, Dragoon, and Black Mage. At the sametime there are people who still find it difficult to play as Monk, Dragoon, and Black Mage due to needing to focus more on their mechanic since they can't adjust to their play style. Thus they mostly just play these jobs to level them up for the job story and/or achievements every expansion cycle.
MCH, in my opinion, is at the right spot to what they want it to be and don't need a overwhelming change to make it fun. The only thing they need is just to expand MCH from now on without adding too many things to focus on mechanic wise. Damage output is in need to be adjusted as well but that is a repeated topic by everyone at this point.
The only thing I can think up without having to completely revamp how current MCH mechanic works is to add a 3rd energy bar that is filled by spending energy to perform Overheat attacks and summon Queen.
It will provide more use for spending energy on Queen and Overheat attacks since combat wise MCH tend to focus on spending these two energy alot in combat based on the player. As of now the main focus on boss fights is mostly to build Energy for queen to maximize single target DPS while overheat is more focused on Trash mob AoE killing or when the timebomb skill is ready or near ready. Having the 3rd energy build up being based on using both overheat energy and Queen energy provides a reason to use both in all situations.
As for how the Power Armor energy maybe drained, it maybe based on skill being used or based on a timer. Skill being used to determine when the Power Armor ends will require proper distribution of energy cost on skills but if timer path is chosen for the design then it will need to have a reasonable active time.
