lmb issues

[Manjubutt]

I was playing for a couple of hours until my lmb was super slow and unresponsive all of a sudden. I tried remapping lmb and rmb to R and T, still didn't work. I was wondering if anyone else has this issue or have a solution for it?

It's most likely lag. There's an option in the settings to add your current ping to your screen. In my experience, anything grater then 150 ping starts to get delayed responses.

Hmm I don't know... my ping is fine. Its just lmb that's the issue, all other abilities are able to combo in response fine.
