Blasters got a bit of a rework just before shutdown that helped quite a bit, and power set proliferation has definitely helped them, too. Tactical Arrow, Temporal, and Atomic are amazing secondaries for Blasters.
My Archery/TA Blaster is level 50 and equipped with only common IOs and the +3% defense and health/recovery IO procs (Steadfast Prot, Glad Armor, Miracle, Numina, and Panacea). She's T3 incarnate, but I haven't yet bothered with any other IO sets, because I never intended to put in a full build. Even so, she is quite super heroic, and I love that Rain of Arrows recharges so quickly I can spam it for almost every encounter.
