Its a World of Warships (WoW) copypasta that started from an analysis of the ships in WoW and a flawed balance suggestion. The OP was incapable of receiving feedback and argued with every commenter which led to the now iconic “Rangar is inherently underpowerd” meme.
Rangar is inherently underpowered. It lacks the necessary attributes to make meaningful impact on match result. No burst damage to speak of, split turrets, and yet still retains a fragile platform.
I would take 1 Conqueror..Thunderer or 1 DM or even 1 of just about any CA over 2 Ragnars on my team any day of the week.
Now... If WG gave it the specialized repair party of the Nestrashimy ( and 1 more base charge).... And maybe a few more thousand HP if could make up for where it is seriously lacking with longevity.
