Naw, lack of CVs is good. The presence of CVs helps feed the collapses that are common in high tiers. Without CVs there's actually a chance that a high tier match will go down to the wire. I had two like that yesterday, and neither had a CV. Good games are really rare in the high tiers, and I savor them.
The real problem won't go away: all high tier ships are glass cannons and can murder each other in a minute. Anyone who pushes up is quickly annihilated by skilled players putting down huge volumes of fire. It has only gotten worse with the addition of the ridiculous Minotaur, whose smoke should be removed, and of course the upgrades to the Khab, which obviously needed to be more OP, since it was Russian.
The solution to better high tier matches is to either (1) reduce the volume of fire -- remove the BB 26 second reload module and make them all minimally 30 seconds, for example, or (2) increase damage resistance -- for example, fire resistance needs an across the board buff, and the number of fires on BBs should be limited to 2, and all other ships, to 1. WG won't do that because they would rather have dead ships than good matches.
That is just the way it is.
You keep saying this but I witness plenty of collapses even in non-carrier games. Carriers are not some instrumental part in the GRAND WARGAMING CONSPIRACY you keep waving around as if "shortening games" actually mattered. What, do you think they pay by the megabyte or something?
