I don't even think they need a health decrease tbh - they are currently underpowered and I think a straight buff (like IPDAI) is in order. I was just objecting to the wasp comparison!
Lets see, digging in right now, the high delay burst PD has 4x218 damage shots in the bank, but only 32 DPS after that. 4*218 = 872 damage per fighter stored up, or 4360 burst damage per wing followed by 160 DPS. That DPS will keep accruing while the fighter wing is out of range/traveling, so doing a direct comparison to fighters with no burst is a little tough, but after a ship has weathered the initial spark storm they don't do much sustain.
Going back to full regen with a standard burst PD would probably be just fine. I don't think 2 burst pd per fighter would be good (changing away from that way back when was a great call!) because its just too much burst vs frigates.
Now that I'm thinking on it, I'd rather have this (a straight doubling of sustained DPS) than IPDAI. Reason: player counterplay against Ordos. I know that right now player fighters are underpowered because of a couple reasons (IMO too little skill support in terms of fighter health and damage output), but keeping flared-fighters extra effective against sparks is a neat bit of "rock-paper-scissors" in fighter/fleet design, and would give a reason to keep things like Gladius/Broadsword/Warthog when fighting Ordos (if fighters got some buffs and weren't underpowered in general).
