5 years playing and nowhere near any of them. Probably will in the next 5 years, and I dont jump from toon to toon either, so yeah, those badges are just plain screwed up to get.
Gratz on getting them.
I'm not even close to most of those, but my first toon to 50 (a blaster, before new defiance) had ALL the time mezzed badges before he hit 50.

My namesake almost has the billion inf earned through normal play (maybe an hour or so per day, sometimes less)...after 48 months. 
Questions about the game, either side? /t @Neuronia or @Neuronium, with your queries!

I don't know if anyone out there will care, but there might be some other people trying to earn the achievement badges through normal game play, so I just thought I would share my experience. After 5 years and 2,300+ hours on my main (storm/psi) defender I have finally earned all of the non epic achievement badges through normal game play, unbreakable being the last one which I earned last night.
So...looking at the epic badges at this point I have:
10/1000 million damage taken,
11.5/100 million healing delivered (with O2 boost as my only heal)
12.9/80 hours held
1.1/2 billion inf earned
We all know that the epic badges are unreasonable to get for most ATs during normal game play, but I thought someone might be interested in just how much progress they could expect to make.
