How to effectively train at ghost pirates/dt's and so on

I find Ludi to have the best training spots from 110-120 on a slinger so this method has been working for me. Also I find it much faster to burn>drop>burn>drop then tele back up to finish it off much faster then to freeze>burn>freeze>burn 1 mob at a time. This is particularly good for Ludi, unless you have any alternatives for training spots at 110-120 then i'd have to disagree with you. Although I know later on training at13x+ would usually be freeze>ship>torp my method would become obsolete, but this is a method for those who are in the 110-120 range
