Flamer seem to be most used weapon for level up. Fast and easy craft, good damage against many critters at same time. I'd like to suggest few solutions for this fast leveling problem:
1. Increase ST requirement for BG weapons (including Flamer)ST 7
-> ST 8 requirement for BG weapons (
ST 7 for LSW and Bozar!)
2. Reduce damage for Flamer50 - 85
-> 40 - 65
3. Reduce ammo capacity for Flamer5
-> 3
4. Flamer harder to craft (requires little more resources)3x Alloys + 1x Wood
-> 3x Alloys + 2x Wood + 3x Metal Parts
5. Flamer Pistol, new starting weapon for BG (Flamer become craftable BG profession level 1)Damage: 20 - 45
Burst: AP 4, Range: 5
Ammo capacity and type: 1, Flamethrower fuel
ST required: 4
I know this doesn't solve whole problem with BG builds, but atleast something against fast leveling.
