It's nice that you want them, how do they get implemented? The special events team would retrofit them on all of their maps that they are appropriate in a few days. How do you propose getting them into the MA where for the most part existing terrains are fixed products? Unless Hitech has an initiative going that I'm unaware of, do you see any BB task forces being retrofitted to converted AH2 MA terrains? Take NDisles for an example, if Hitech made the project files available to me, yes I could add a BB task group to each port. At the same time every field sitting on the water would need at least two shore batteries added or NDisles would be a 16in turkey shoot. Every single HQ and strat would be sitting ducks to 16in fire no matter how many shore battery.
As for smaller carriers, it wouldn't be much different than attaching two CV task groups to each port at which point terrains that stable game play was designed around single task groups would have their stability dynamic changed. And a direct swapping, then you give up the real purpose for the large carrier and the force it projects as the package size it is designed for. And when one side leaves the CV\BB together as a super fleet, in some strategic ways it's almost cheating the other side to how it projects force inside of a sector with the smaller numbers we have these days, until they realize a super fleet is hard to not see by bombers. Massing task groups together seems to inspire dropping everything and bombing the whizz out of them versus a single task group is often ignored until it picks a nice balanced fight with an enemy field. I've had a lot of reasons to observe how my terrains get utilized, this being one of them since I introduced the BB task group onto my terrains and into the game by Hitech's request.
My last two terrains for 10x10 are packed to about the max for play stability with task groups and what their package is projecting as force. My next terrain is an experiment with the smallest pond you can stuff a CV\BB task group from each country into and have the fastest reasonable ship to ship contact with no real place to run. Thank world of warships for giving me some clues about that.
The core CV task group is a well balanced package for base capture initiatives. Expanding it with an extra mini carrier, why. Now you have two mobile flack barges to expand the suppression area around a single airfield and basically parking two airfields at a minimum 3 miles away from a single airfield by design. All of you have experienced the occasional misfortune of two even three CV task groups moved next to a single airfield. Not a very fair and balanced game in the Melee arena at that point but, it's "rare enough" to be acceptable. Two as a standard would not be a balanced package in the MA where balance is the primary concern when building terrains.
