EK 2 second cooldown healing questions

Hey all, had a couple questions about the 2 second healing and how you all are dealing with it.

Before the update I tried using a gaming mouse for EK but I found it extremely hard to hit all the actions I need with just my thumb and had to go back to keyboard and felt way more comfortable. After the rebalance I feel like maybe the gaming mouse is a better choice now with the new mechanics. Has anyone made the switch from keyboard to a gaming mouse?

One other thing I am having a hard time getting down is the 2 second cooldown for healing. I have come so close so many times to being sent to the temple because this cooldown for me is just really throwing me off.

I love playing EK but I have enjoyed playing MS and RP just because I can use my gaming mouse and feels way more comfortable to use the mouse. Would love to hear from others what their experience has been like. Thank you!!!!
