yep. the hadron and king combo are a must in some builds because they take a ridiculously long time to reload without them. the jotun is a really good example of that, without any reloading boosts the reload time is so awful. in weapons like the mammoth or the mastodon it would really help but the issue there is that these cannons are heavy as all hell and cant be mounted on a hadron. same goes for typhoons. ive come up with a few combinations for them though and they work well.
