Here are some thoughts on the prop damage system... just thoughts.
This might be problematic, especially if there are minges online. Explosive damage is a good idea (possibly using weapons like C4 and Grenades), but I do not think bullet damage is a good idea, because of how easily it can be abused. C4, Grenades, etc. should be able to be purchased through a black market dealer or a heavy arms dealer.
As someone who enjoys building bases on DarkRP servers a lot, this is extremely problematic. I believe if you are raiding someones base - without prior knowledge to anything inside the actual base (aka the layout of it) - you should have to struggle a little in order to get in. The idea of giving props health and allowing explosives that can easily kill multiple people in the first place, let alone guns, do damage to props essentially ruins base building.
Back on old tdrp I thought the Ghoster and the Super Ghoster were pretty good raiding tools. Hell look at the "Ghoster" the police have, if you have no forewarning of them coming you are boned, they are coming in your base and you don't really have defense if you can't react quick enough. Not just this, the only people who benefit from this type of update would be donators who get a higher prop limit, and the people who have all the money that can afford big raiding tools. With the current rules, as long as they are followed, I don't foresee many issues with raiding.
Not just this, imagine you're the new person trying to get into playing on tdrp. You got a pistol chillin in your base with a starter printer that takes 15 mins to break even with. Now, not only do you have no money, you also are relatively defenseless. Next thing you know you have people blowing up/shooting your props and you're dead because apparently, people can rip through props. Are you staying on that server after that just happened or are you getting onto a different one?
Now, I understand realism should be taken into account but you wanna have fun and play the game. Not get shit on 24/7
Tl;dr - Raiding shouldn't be a "1v1 open ground" situation, you're breaking into someone base. You should have to struggle, if you want to make it easier just add better raiding tools, not game/rp-breaking mechanics
