The first couple days of the patch were really bad. One time I cast Aetherflow, it went on cooldown, but I didn't get any stacks. The past two days, it hasn't been as bad for me. The only thing I really notice is a lot is I seem to have to spam Whispering Dawn for about 10 seconds before Eos will start casting it. Don't know if its due to lag or something else, but it worked fine before the patch.
