1. what do you think about making rocket puppies' rockets destructible by weapon fire? so a gunslinger could shoot it before it gets in range naturally u can swat at it with a sword but the explosion might get you still. i can see a bomb work here too.
2. how about having some Gun Puppies move like on monorail tracks of sorts. in other word allow the gun puppies to travel between two points (if applicable) clearly visible by the track configuration (like a line with two circular ends maybe some tracks can be circular) while still having all their normal skills and targeting. this would add more challenge to them. they would have to be slow enough for knights to catch them and i guess u can stop them by getting in the way of the path its on, but shield bumping wont work.
HOW COULD YOU SUGGEST SUCH A RIDICU-oh wait, that actually doesn't sound that bad.
It might be a bit hard to shoot the missiles (or bomb them) when things get hectic, but it might be a useful little trick you could learn. The only problem I think would be that the missiles could explode and hit a person who dodged it. In theory, a party should try to be a bit more cohesive then that, but let's face it: unless you're doing it with friends (or mike chat), fellow party members are generally mute suicidal macho men that seem to have been dropped on their heads as a child.
I like the tracks idea, but it would make killing them with swords very difficult, especially people like me with their strong but rather pitifully slow kamarin/troika/sealed sword/whatever. Maybe track puppies would be nerfed in some way? Maybe they cannot move their sights (i.e where they aim), relying on the tracks to aim them, so that killing them simply involves finding a blind spot or sneaking behind them. I dunno, just adding to the idea.
