I have been booted many a times by people who cannot take a tower from me in AV it seems to be a huge problem because I have even heard people say they will not attack a certain tower so that person gets AFK’d out and they can just take it after. IDK if this would help but the defensive buff you get from protecting the tower (that might just be a retail thing) should be put into Classic WOTLK so it doesnt AFK you for actually playing the objectives.
this should be high on the problem chart for things that need to be fixed
