Attachement vs Unit Model

[MateoSoetsu]

Am I correct in the logic that a low file size custom weapon/shield attachment on a wc3 unit is much better than downloading a custom model?

Will a lot of custom attachments make the game lag?

Attaching a simple sword to a villager is more file-size friendly than reimporting the whole model, sword in hand, if that's what you're asking.

I'm asking if I use a custom model say 20+ times at once, then if it is possible to achieve a similar effect using simple attachments it will reduce download time, load time, and lag?
