Combat is so slow, and it gets slower and slower the more enemies are on screen, which seriously limits how you can design encounters. Please don't make it any slower. It's literally turn based. How much slower can it get? It's your turn, select an ability, click enemy. Wait for your next turn. You have all the time in the world to analyze the situation and decide what to do.
I really don't feel this way. I honestly think what you're experiencing is the delay when the AI makes up its mind what to do on some NPCs when it gets busy, which is specifically what I left out of my feedback. Moving and clicking your action etc is really only a matter of seconds at the moment.
To handle larger combats where there are a lot of bad guys, its really easy. DMs have been solving it in table top for years. Either make fewer, more powerful bad guys, or have some of the minions/grunts turn up in waves. Solving the AI "thinking" lag would also help.
