I just want to know are barrel and jar will be prime target forever? Or u guys have plan to deal with it?

I'll be very upset if I have to burning bunch of ankh bcoz I keep failed to freezing mob/kill mob,not bcoz I'm late to charge my ice bolt/lightning strike or have problem with my conection,but bcoz my light and ice keep hitting those barrel and jar,which is the distance is twice away from mobs that surrounded me.
