This this this this and this. The reduced smoke is the least of my worries at the moment when captaining my dd. I get hit, modules are broken, I hit the repair button when there are no imminent salvos incoming and it's all fixed. Then somewhere in the middle of my repair cooldown I get hit again with modules broken such as steering or engine which makes me unable to do ANYTHING at all than to witness my imminent death other than praying to the rng gods you either go undetected or the opponents miss all their shots. Same applies for the CL class although in most scenarios it won't result in immediate death unless in close combat/many opponents in your vicinity.
I don't know what they changed compared to the previous patch but this seriously has to be looked at. Either by reducing the repair cooldown timer or looking at the module damage system or reducing the repair time of modules themselves. If something like this happens in WOT while already having used a repair kit you have at least SOME survivability since repairing a dead engine by example only takes a around 10 seconds or a bit more. In WOWS you have NO survivability with a dead engine or a stuck rudder which seems to take forever to get fixed by itself. You're a sitting duck because the rng decided you should be and there's nothing you can change except waiting for your repair cooldown which is seriously frustrating.
