I agree that the manned turrets should be more easily identifiable and repairable, but I don't agree that there should be more of them.
I once got shot down four times in a round by the invisible autolasers, so they are not altogether useless. Nevertheless, I think getting rid of them altogether would significantly reduce the (over)load on the server CPUs, which is what causes most of the lag (and I believe the Windfarm is the cause of similar overload on Ryloth). The lack of autolasers would be more than offset by having repairable manned turrets, and that may mean reducing the hit strength of the Deflection Towers to compensate. However, I wouldn't reduce the strength of the Towers simply to reduce the length of the round.
"The map lasts way too long" is not an opinion I share.
We ran two rounds of Yavin on RT's server last night and it remained fully populated thoughout both highly enjoyable rounds. It is the possibly the best map in the whole mod for eliciting a feeling of being there in the film, and it's highly popular.


Mmm... vanilla!
