We all know that turrets were given a time limit of up to only five minutes at a time, as a result of afk farming (which I never really saw people do much really and could be done with pets and what not but thats for another topic).
My suggestion is that every time turrets are overcharged, that five minute time limit is reset. This way people still cannot go afk and people who use them legitimately are not penalized.
Cmon Anet I know you can do turrets right!
