All his stats were quickly proven wrong in comments. Armor is the only thing that matters, as it is the only stat that affects how many hits you can take. Recovery is almost worthless, because having the opportunity to hide for 1 second, 1.5 seconds and 2 seconds is minimal assuming you found cover. (this is all for PvE) Not dying in three or four shots compared to 2 matters way more. The Titan moves much, much faster than the Hunter. The triple jump is the lowest and shortest jump out of any class. The only time triple jump has a distance advantage is when you are dropping down. A platform to platform jump at equal levels or going up in height, both Warlock and Titan are better jumpers. It is stupid, the Hunter should be the most mobile class because it is inherently the most squishy. I am 150+ hours in on my Hunter, she is garbage for mobility, toughness, supers in lvl 20+ game play, and Raids as they stand.
I'm not sure how you're having trouble. I run max agility on all 3 classes just because the others do nothing and I like to be that little bit quicker. I have no problems surviving anything. The hunter also definitely feels the fastest of any of the classes. I don't feel any tougher as a titan either. Glide and hover are both useless to me, I just have to put up with them. I'm not a fan of triple jump either, I prefer higher double jump. You won't convince me anything is better.
As for raids, hunters are the best class outside of the obvious self res warlock. One shotting hobgoblins, oracles, and supplicants is amazing. Not sure what to tell you.
