I disagree with Enforcers taking a long time to kill. 750 armor is enough to protect against smaller shot size energy and kinetic, but not enough to meaningfully defend against armor crackers - either heavy mortars or any of the armor piercing energies (heavy blaster, phase lance, am blaster, most large mounts) will deal with it in short order. Because its relatively small (destroyer sized) it doesn't have a huge number of armor cells either, and 5000 hull is ok, but nothing special. I will admit that it has enough armor to deal with the kinds of low penetration weapons that frigates often have, but anything destroyer+ has the weapons to crack it.
So its armor is strong for a destroyer, but not strong enough to actually withstand any armor piercing weapons. Its shield is
awful. 1.2 efficiency is not quite the worst as a raw number, but unlike other low efficiency shields it doesn't have the flux stats to back it up. This really needs to get changed to 1.0 imo, like the dominator and Onslaught, for the Enforcer to be competitive.
The 750 armor does help against light fighters, because they are using the same low caliber weapons as frigates, and the Enforcer can mount a good flak screen, which helps against swarms and missiles. So I'll give the Enforcer points for fighter defense: probably the strongest of the destroyers in that role. But its also very slow, so can't catch and kill the fighters.
...An single enforcer can take longer to kill 1 on 1 than many capitals. ...
If the capital is a converted pirate then maybe, but I doubt it.
