Suggestion for balances from a low-elo player, take it or leave it :D

Roleblock immunity is too strong. The only thing that arsonist should be immune to roleblocks for is cleaning gas off themselves. I'm not even sure if escorts can roleblock that in the current patch. If escort roleblocks arsonist during 'Pyromaniac action' then the escort will be doused. This makes for a serial-killer like scenario: Did escort get serial-killered (?) by the person they visited? Did escort get doused by the person the visited? Who knows. :)

Also, I see in your idea that a 'Pyromaniac action' can be used to douse and ignite a single target. Does that ignite all other doused targets?

Being able to kill 3 people after two nights is strong...but i'm not sure if it really is more powerful that SK/WW. Werewolf can kill minimum of 1 every two nights, but every other night they are useless. SK can kill 1 every night, if they are lucky, but they can't kill through night immunity. I'm probably wrong, but I think your suggestion for arsonist would make it the most powerful NK role. To balance, the night after using pyromaniac action to douse 2 people (not when using pyromaniac action to douse+ignite) the arsonist becomes doused, forcing them to take a night to clean the gas off themselves.

This suggestion gives 'pyromaniac action' a Risk vs. Reward element. A major part of arsonist play is knowing when to ignite, and using this arso ability delays ignition by one day. You might say, well what's the point? Why not just douse one person each night instead of two people in one night?

I think the ability would still be useful because: Taking a night off can makes jailed/roleblocked people suspect. On the night off, claim that you were doused. In a double arso game, the 2nd arso can ignite while the 1st arso is cleaning off the gas.

Those are all the reasons I can think of, and I'm starting to think it's not a very good idea. lol
