Hello, I have spent some time leading a low-level campaign, but I think that in the near future my PCs may start at least thinking about better quality gear. They are already saving for bolt weapons, sure enough. Maybe the game won't last that long, but if it does - sooner or later they will think about getting something better.
The problem is... okay, maybe my perception is a bit tainted from the TT game and in the fluff (i.e. books), but after bolt weapons things don't look too impressive. Take your average plasma pistol, for example - a weapon supposedly designed to kill space marines or even destroy light vehicles, with an impressive price and some unpleasant drawbacks. Yet with its current stats, it has a very large chance to do NOTHING to a space marine - who gets 2 points of armor carrying over from his power armor, say, has unnatural toughness and T bonus of 5, thus soaks 12 points of damage from a gun with damage of 7-16. Unnatural toughness and T of 50+ makes a plasma pistol/gun pretty much a joke - a plaguebearer will be a serious problem. Heck, a meltagun (damage 6-24) has a notable chance of doing little damage to a marine-level opponents. By TT rules and fluff, this is a gun that wreaks havoc on tanks, Tyranid monstrous creatures, or evaporates CSM champions. Yet it's pretty much worse than an astartes bolter (lower damage, no tearing),.
Is it just me, or would the high-power weapons need a little boost to be effective at higher levels? I'm thinking of giving plasma and melta weapons (except the multi-melta) an extra d10 of damage in order to preserve their position as a cut above the bolt weaponry. Alternatively, I'm thinking of using the Deathwatch stats (never quite understood the whole "astartes bolters are OMGWTF better), again with boosts for non-bolt weaponry. I want to make sure that for players, the moment when they get their hands on a plasma weapon feels... special.
