An Iconoclast can destroy a Dauntless in one turn, doesnt make it very likely tho. I like Daunts but I just dont see them being better. The Endurance is tougher and their armament is better suited to supporting other cruisers directly instead of acting as heavy escorts like Daunts. When exploited to their strenghts they are quite superior especially in Armageddon lists when you can partner them with a battlecruiser for some cheap smackdown. These were fine at 120, the extra turns are not required for their role and suits only to drive the cost up. An extra shield option sounds ok but then Strike cruisers are pretty overpowered with 2 shields @160 and I dont see an Endurance being any less overpowered for its price with 2 shields @125-140.
