I can't believe that people think taking one extra hit as a striker is somehow not imbalancing (note word choice; not necessarily OP, but certainly not balanced).
Let us assume Bacon never runs back to base to heal and survives for 2 min on average between hits . He's good at dodging, and so never gets hit. That extra health bumps him from a 4 min survival time to 6. A pretty good increase.
...Though the reality is that more likely he gets hit three times, kills the enemy, then runs back to base to heal. Not to mention it feels like he's constantly using ce rez; you take him down/force him to retreat, but he's always back in tip top shape in seconds (and that's for ALL elite strikers; they rarely die, just fall back for a bit, *especially* if you're a slower class and can't catch them).
Then there's the ability bar imbalance that I totally forgot about. Guardians and recons lose their special ability when they get hit, but not strikers. How many hits do you think a striker can negate in one boost bar compared to a guardian? Or recon? What about recharge rates? But that's a whole other thing.
Lol.. those 2 hits make a huge difference when you're at even, or near even skill levels with your opposition, or when somepony is teaming up on you.
If it normally takes 2 hits to kill you as a striker, being able to resist that one extra hit could be considered huge.
