I think an important question to ask is where a combat interceptor should stand in relation to Dramiel.
Dramiel has pretty much all the properties one would expect from a combat ceptor, reasonable tank/damage, great speed (sub-warp and warp) and agility, great control, low sig radius, versatile weapon system bonused for projection all for a quite fair price of 48m ISK @Jita atm, with potential for bling to improve performance.
Combat ceptors on the other hand, fail to tick some or most of those checkboxes. Both Crusader and Claw have only two mid slots, restricting them to fleet and kiting roles (can’t do the latter well, no comment on the former). Raptor looks like it’s getting there except it’d be armor tanked and the CPU/PG falls short for a viable shield fit. Taranis has some strong damage potential with passable tank, but when you pitch it against Dramiel, it falls short on most criteria except for price and facemelts.
The combat inty advantages are the MWD sig bloom reduction and tackle cap use reduction, which apparently are not strong enough to balance it out. For a hit-and-run role, inties would spend most of the time fighting scrambled, and drones/RLML are still a problem with MWD on. The tackle cap reduction is nice to have, but there’s not much to write home about it. The difference in cost also seems hard to address- people will either pay an extra 20m for better performance or combat inties will end up strong enough for the Dramiel to be too cost inefficient in comparison. Not to mention that pricing is not a reliable balancing factor at all.
Anyway, most of what I said above comes from my limited solo PVP experience and pyfa warrioring, so take it for what it’s worth.
