I don't think you have to say its easier when you are top tier, cuz that is the case for all ships in general. I would say all DD are better when they are top tier lol.
The issue really is how often are you really top tier in say 20 games.
Also although max damage is high on it, it is also subject to rng, I would not say its always gonna kill a dd in a single hit. RNG is +/- 25 percent range.
I think the straight description of what this new IJN YukiKazi is. Its like an up tiered Kamikazi, except for its tier, it has short range torps of 8km but torps are fast.
What does this mean for you if you play it.
Well in the world of carriers, radar and hydro and other destroyers in game you have to be very careful and for you to be effective you have to play at dangerous ranges where if ya get spotted you likely get deleted or take heavy damage.
As a typical destroyer player 8km torps means unless ya using the torpedos for denial of area or hoping to get lucky, at 8km range torps, you are going to get as close as 5km to 6.5km to get your torpedos off to have a good chance to hit em. You are not gonna be launching your torpedos at 8km unless they coming towards you.
This close range of attack means its gonna be very dangerous.
Against other DD, the problem is it has 2km less range than some DD per tier or even lesser tier. So they other dd can hit you from farther away. As well the reload being what it is, although the guns are good, you cant out dpm other gun boats.
So you are in this no mans land kind of, you are not a gun boat, but you are a torpedo boat but you have short range.
So its like in a way a Japanese Russian destroyer hybrid, reload doesn't make it able to gunboat and out dpm other gunboats, and range on torpdeos is short. Or you can just call it an uptiered Kamikazi with short range torpedos for tier.
Would you choose to play this over other IJN premium DD? Probably not unless ya bored. Is it noob friendly? With matchmaking what it is, and with the amount of planes, radar, hydro, and other dd you gonna face most of the time, I would say no its not noob friendly.
