DoTs must always be up because if they're not you risk missing a tic of the DoT because of how the mechanics behind DoT tics work. If you can flawlessly reapply all your DoTs the second they fall off, then yes, that is the most efficient use of MP. However, realistically that will almost never happen. You'll have to move to dodge a move or be attacking an add or passing rot or something, there are practically no fights that you can just stand there and throw out the ideal rotation. That's why you want to err on the side of caution and clip your DoTs early if you think you're DoTs are going to fall off at a bad time, because you can lose a lot of damage if your DoTs aren't all ticking whenever possible.
