But is it more difficult to play? I think some people just want to make their job sound like a great challenge compared to the alternatives. You can take this with a grain of salt considering I've really only been putting effort into MCH for maybe 1 1/2 months. But I seem to pull respectable numbers from what I can tell. I find MCH, for the most part, a little easier than BRD. I explained some of the reasons earlier in the this thread. And when I say that I don't mean to say that BRD is so much more complicated and challenging. Not at all. They're overall probably similar in difficulty. Each jobs with its own ups and downs.
The main challenge I find with MCH at my current skill level is identifying procs with no ammo. I admittedly miss a few here and there. And I've had my turret cleaved more than a few times in A3S. I've gotten better about replacing my turret asap in those scenarios, but it helps to have communication from other raid members in case I miss it. The other thing is if you're pushing legs much faster than progression pace in A4S. Managing CDs at that time becomes a little annoying. Instead of popping wildfire at the beginning of each leg you may have to wait until after adds if you want your wildfire to do much of anything. Takes some adjustment if you're not used to it. But it does for any job.
BRDs in A1S should pull ahead of equally skilled/geared MCH with the same comp if they are keeping both Oppressors dotted at all times due to BRD dot potency alone. If they're not doing this, then yea, it's not difficult for a MCH to pull equal or slightly better numbers. One 30s dot is easier to manage than two 18s dots. The dot upkeep on BRD, especially while handling adds, requires more thought to GCD management. And if you drop your dots on BRD 2 GCDs are required to correct the error. Or 4 if you drop dots on both Oppressors. Much greater potency loss compared to dropping Lead Shot for a GCD. Things to consider.
