I had a ridiculous series of battles last night, every single battle was lopsided one way or the other, and it got me thinking. Pretty much everything people complain about at higher tiers other than radar working through islands (should be fixed period), is a spatial problem.
Tier 10 maps come in 3 sizes.
36 Km x 36 Km = 1296 Km^2
42 Km x 42 Km = 1764 Km^2
48 Km x 348 Km = 2304 Km^2
Compare that to the ranges of some of the wepons in games.
Yamato - base main battery range 26.6 Km - 2222 Km^2, more area than all but the largest map.
Russian CA range - 11.7 Km (greater than a Gearings base main battery range) - 430 Km^2 33% of the smallest map, 18% of the largest map
16.5 Km torpedoes - 855 Km^2 65% of the smallest map, 37% of the largest map
Now look at the way way meta is currently going.
DDs won't cap unless they can get into strong cover, or the enemy radar ships are either all dead or accounted for.
CAs hug rocks because they don't want to get deleted by a BB salvo
BBs snipe from maximum range, because they don't want to get heat spammed or torped to death
CVs are super rare, because all they can do is spot for the first part of the game till ships take significant damage to their AA guns.
Lots of people hate cvs because they can perma spot indefinitely.
The game keeps getting dumbed-down, and skill keeps getting removed and replaced with luck. Hence the reason play keeps becoming more and more passive. You make one mistake and all those ships that where outside detection range or just behind that island will light you up, because they are within firing range. Reliable Team play is non existent, unless you are in A division with people you can trust.
Imo, this all comes back to a spatial issue, the maps are to small for all the ranges involved.
Two possible simple fixes
decrease all the ranges - Unless the code base is utter garbage, this should require almost no work.
make the maps larger - Again this shouldn't be very difficult, its not like they are developing a completely new concept
Make CV planes have fuel limits, so their ranges are limited.
Lowe the AA ability of ships to give CVS a chance.
what this accomplishes.
Team play is encouraged, because going off on your own will limit you ability to deal damage to the enemy as they are further away. You can also end up in a real hurt locker, if you run into a group of reds because you have no one within range to support you
Its easier for DDs to cap, spot, and flank. However they will be punished more harshly for mistakes, because your support is out of range, and the enemy can focus on you more.
CAs can spend more time in the open, because half the enemy team isn't withing firing range. But they can't camp as much now because they run a higher risk of being flanked, spotted and/or torpedoed by a DD, or taken out by a CV. Not to mention since their range is reduced they must move up if they want to deal damage and help the team.
BBs will have it much the same as CAs. If your spotted by a DD it's not so bad, he might be the only one within range to attack you. No more getting spotted by a dd and then lit on fire by multiple ships HE spamming you. On the positive side wen a CA makes a mistake you can really put the hurt on him, because he has less support, and is out in the open, not lobbing shells over an island with impunity.
CVS Have a real chance of damaging any ship in the game, because AA isn't so dangerous, because ships are more spread out so you might only be withing range of one ships AA guns. Also its not as powerful as it currently is. However, your planes have limited fuel/range, so you can't hide at the back of the map, and you can't perma spot. When you are spotting someone they will be less likely to take damage because your support won't all be withing range of them.
Honestly, i think this would push the game in a direction that's much more team oriented, because every type of ships is heavily punished for yoloing, and hanging back.
