Some observation, why megapol cannot have their own issued weapons? for instance there is a space ranger pistol & rifle which are not used by space rangers since they do not exist - or gonna be implemented don't know - but i think it's very strange that a well enstablished and founded police corp uses rusty niners...ant least the rangers one might be rebranded as megapol pistol and so on...since RCF has a dedicated carabine...
1. Megapol from XPiratez and Megapol from XApoc are two (vastly) different organizations. Same with Marsec. Please stop mixing the games.
2. They are a police force. Period. They're reluctantly sponsored by the Govts, but I assume the sponsors are not really interested in having a strong police force outside their control. So they get shitty equipment. The 'plasma upgrade' is most likely funded from outside (big factions) or forced on the Govts by Star Gods - to "handle these pesky pirates wannabes once and for all".
3. Space Rangers are a membership organization, not a faction per se. It's mentioned in the Bootypedia that some (most?) high ranking members of other factions are also members of the Rangers. They're an evil mix between a gentleman's club and volunteer militia. They sure as hell can afford their own line of weaponry. And they are probably not going to share it with a bunch of dirty beastmen that call themselves the police.
They later carry also plasma weapons, but again these are a bit too excessive for them, how to replace with laser ones? the plasma should be an exclusive or mercenaries and star gods, while gauss might be a bit more common, though in the mid-higher factions, like mercenaries and marsec, though in xcom apocalypse the latter had theri weapons too, so some dedicated firearm may be a nice contribute
1. Plasmas -> see point 2 above.
2. Marsec does have their own weapons. Just because you haven't met them, doesn't mean they're not there. For the n-th time - play the mod more, before making suggestions.
Lastly - asking for total conversions (like the swapping of weapon types - which would require re-balancing the entire mod) or changes that are of a 'I don't like it' category is a nice way to get permanently ignored, at best. If there is so much that is wrong with Xpiratez that you have to complain about it on and on and on, then perhaps this is not the mod for you. You can either choose some other mod or modify XPiratez on your own - it's open source and easy (technically speaking) to do so. Dioxine is open to suggestions on how to improve the mod on a objective level - not to adjust it to everyone's liking.
