I’m not the greatest at prayer flicking, players who are good at it gives them a big advantage in LMS. It becomes pking in sense where we have to switch weapons and pray change constantly. Removing prayer would make LMS different from pking and give it its own feeling.
Since prayer points don't drain in LMS I'm assuming you mean prayer switching? LMS should be seen as a way to practice PvP safely and since prayer switches are a big part of that, it wouldn't make much sense to remove that aspect.
