LOTRO is a bit of a funny beast, and you really end up needing to use a rotation that includes timers. You cant just shove a whole lot of key presses and hope that one works like some other games.

The worst part of that is that you need to setup a rotation on a best guess scenario for reactive skills, and some of the more important ones, like Kick you end up needing to just handle manually. Some reactive skills makes sense to cause a reset in a rotation, others don't. You do end up with a fairly complex configuration that is not 100% accurate in always utilising every skill in the best scenarios, but with some planning, you can make sure it always does something.
