when fighting xt for hardmode or easy mode an easy way to only get to active trash piles is to position so he is inbetween west or east trash piles like shown in this video([ame=http://www.youtube.com/watch?v=Zs7s5n4fscM]YouTube - After Midnight XT 10 man Hardmode[/ame]). In doing this you only have two active piles of trash and less randomness of bots to worry about.
