I'm currently a level 2 pyro, and he's almost completely useless. Every fight has been with guys who have only melee weapon attacks, or major resistances to fire. Then there's the high SR. Five sessions and he's only been useful once, and it was against a skeletal dragon.
What kind of game are you playing in that you are encountering fire resistance and skeletal dragons at second level?
I have to agree: what kind of game are you playing?
In all my years of playing, I've never encountered SR or Fire Resistance at levels 1 or 2. I usually don't see SR show up until at least 6 or 7, and when I do, it's usually paired with Fire Resist, since it's generally on a demon or devil.
I mean, seriously, a skeletal dragon?! At 2nd level?!
The weapon issue, well, yeah, that's a good deal more common. I know the APs involve mostly monster types, but, in general, when I run games, the opposition is mostly made up of weapon-users, and I'd say it's a pretty even 50/50 split between weapons and natural attacks in the games I've PCed.
You guys are kidding right? PFS. Like, legal PFS. I'll hide the names of the adventures so as to not spoil them. If you haven't played them, and you look, unfortunately it's still spoiled.
