I did story arcs mainly solo to 50 with my ice/ice blaster, and the amount of times I needed to use a break free was probably less than 10 times. I cant speak much for the other primaries etc, but I had freeze ray(ST hold) and then bitter freeze ray(same thing, only better) and once you learn which enemies have the holds or stuns, that's who you prioritise with like an immobilize, then move out of LOS, or hold, or put a slow or -to hit on them etc. I didn't even take Clarion for my blaster...I just went for more dps. I figure the best defence from getting mezzed...is kill the enemies before they can mez you. 😄 As was pointed out somewhere above, blasters and other squishy types have generally learned to work around their limitations, with relatively no issues.
