I'm going to throw a different perspective out here: As a relatively new player who never experienced earlier iterations of the job, I love the MCH design and it's my preferred DPS out of those I've tried so far. I love the mobility it has versus positional-based melees and cast-bar locked casters, and I love the lack of random procs vs dancer and bard.

I'm playing with 80ms lag (US east coast to west) and have no latency issues with singleweaving during hypercharge. However, it seems like the latency issue could be completely resolved by changing hypercharge to simply give you 5 charges of a resource that you could then consume whenever convenient for either heat blast or autocrossbow.

Honestly the only thing I personally would like to see added is an AOE battery spender.
