1. An SG flamethrower.
2. Rework Pyromaniac so it can work simply with fire weapons [Solar Scorcher f.e]. Weapon is not ammunition type, so don't worry, Gecko's Breath Pancor Pyromaniacs hype should not intensify. <<< I heard that close thing is going to happen
3. Change Molotov to fire damage.
4. An inciendary grenade maybe?
5. DIY bases and caves/bunkers should also be purchasable without any faction.
6. NPC factions, make them more interesting! Currently the only good features are almost all-in professions and trolling PKers with reputation. Quests and boring and too easy to fuck them up [f.e the rescue missions are random encounters, but just in a specific zone, and they aren't likely to appear in pip-boy]
7. Some poisoned melee [f.e knife] would be fine.
For me - that's all.
