It would have been much better to work on finding use-cases for the existing tanks rather than adding new tanks with no use-cases!
This is questionable game design as it basically adds complexity without depth. This is a major issue that the HOI4 designers struggle with (a recent example was the addition of different types of recon).
Especially taking into account what happened with the MTG ship designer. But I understand the need to add some shiny features to put on the DLC product page or 3D models (such as the armored car in previous DLC).
A module system is only interesting if:
- several significantly different templates for the same unit are viable. Otherwise —and this is what happened with MTG— you're simply adding extra clicks to achieve what could be already done before. In MTG, there is for example only 1 optimal detection ship template, so why force us to click on all the modules? Same for other ships.
- the choices you make on modules actually have an impact. Making people choose between Armor A, Armor B or Armor C is useless if difference between those modules is negligible in the final fight calculations.
- (applies to single player only): the AI is competent enough that designing templates actually has a payoff. In MTG, that isn't the case; any template will stomp the AI, so, after the first few hours of discovery, why bother designing templates? (navies are actually not needed in single-player as the AI kills all it ships purposefully on naval bombers, but that's another topic).
Additionally, no true effort was made to balance modules MTG in subsequent patches. Balance in a module system is essential, otherwise there are optimal templates which defeat the very goal of having a module system.
Question to the devs:
Currently, we already have many different tanks, however people overwhelmingly use the same ones (medium tanks).
What makes you think that adding a template designer is beneficial to the gameplay?
What's going to happen is that people will build the same optimal design repeatedly, with extra clicks now. It would have been much better to work on finding use-cases for the existing tanks rather than adding new tanks with no use-cases!
