Because its guns are unique variants of the H44 guns, meaning it has BB5 range and damage.

To correct you means you got more damage , range stay the same as h39/h41 have same range like h44 with light shells

Why J39 and other new BB 4.5 have only 7support slots whean H41 have 8support even Opro EBB have 8support spots
Ok its slow beacause of bb5 must stay beter , but why 7support spots? test team and mods alwayes saying EBBs are for lvling why no in this case

And i saw structure strenght i dont know how much difrence that have but J39 have 100,h41 160,h44 161 and h39 100 Is that mean h41 is stronger ship than j39 (can take more hits)? 

It is not in an ideal case, it is in a regular gameplay environment and you will see most skilled KM players doing it regularly.

Blinding is also easy, even in GB. 

You either balance for all the regular team game modes or you balance for GB, you can't have both. A ship is either good in a team play or good in GB for you to play alone, they are 2 completely different environments. I already said that KM does not excel in GB, it is not the nation's environment. As an example, the QV excels in gb, but a bb room is not the perfect environment for it which is why you don't see many of them in a serious HA battle.
 
Where KM excels is in a BB room and you have just said it is ok there. 

Every ship can slingshot, but not every ship can do it successfuly. Gun placements, ranges and overall hull is a very important factor. KM has that, others don't.

 

I'm happy that u keep replying me and tell me the alternatives of my views.

For normal players, GB is the main gameplay in this game as it is interesting and competitive environment as all players fight for their attacks to get good exp.
BB room is just few during event. No event then No BB room

In GB, much more issue hv to be faced such as SS, planes, BBs from dark area.
GB is a place where small ships could do sth for the team like AA, AS, scouting, etc. 
Blinding in GB is depending on the situation.
(SS FF is a scout, everyship could be a scout, i hv tried to use a ff for scouting under a big cloud and make the em bbs confusing. ;-)  The km AA is good to kill approaching fighters/scouts/bombers but not skillful scout user.) 

I'm not asking for a oped J39. I just wana get a fair EBB4.5.

It is not an EBB 4.5. 

I think I hv to stop the discussion.
I hope J39 can run 23/39 with normal setup with a patch for balancing BB4-5.

Good Job, Thanks a lot, nyerkovic.
You always show your patience to answer me and explain the idea of this patch.
I'm sorry abt the discussion with emotion but i'm sad to use a 100medal ebb with little little advantage and not for exp grinding.

 

For me, i call it as EBB4.5 becoz it's between ebb4 and bb5.

If it is better than bb5, i will call it ebb5.

To Identify the 2 ebb3 easier, most players called them 3bb3 and ebb3.5.
There is no 2 ebb5 but it is between the ebb4 and bb5 according the level of ships.  
It is a problem of identification system. Calling J39 as EBB5 would cause misunstanding.

It is weird to see every new KM ships is balanced for HA or normal BB rooms. I thought HA was for Kaiser playground, not for the tiers below it. And normal BB rooms is now practically extinct. As almost every KM BBs balanced for BB rooms it would be a change to see a new one balance for GBs.

U can hope but it's not going to happen. Look at bizzy43 as an example, it got more fire power and also reduced speed (if u set it armor the same as normal bizzy).

I'm not doing HA, J43 is just another harbor queen if u get it, like my bizzy43.

H41 is the best for grinding crew exp to 120 in GBs. H44 11k sunk repair cost is a serious disadvantage for player like me (don't have high lv cv).
