As a Jedi main I am already struggling with the FP drains being far too high. Sometimes I lose all my force to an ENTIRE clip of E11 whilst holding block. This should be at least two--and by the way gunners have far too much ammo: because these FP drains are so low, I have seen players with enough ammo to kill TWO BLOCKING Jedi during a round.
This is hardly a generalized example of how saberist actually plays on open. First of all being a jedi main and still struggling? What the fuck have you been doing while not applying yourself playing one of the easiest classes. I'm not going to tell you how saberist should be played but I do have a lot of experience with it and fact of the matter is, saberist can tank anything thrown at it in reasonable amounts, you can choose your battles far better than any other class, simply due to rinse and repeat nature of fp regeneration. Fine, then you found yourself in a 1v1 situation that you thought you could handle, but the gunner was far more accurate than you with your 1-swing instakill weapon; the rationale is you got far too cocky, did you even try forcepowers? - It's a rhetorical question, as the saberist kit is far over packed with things that can kill gunners in 1v1 with no huge complications.

Speaking of high' E-11 fp drains, I know for a fact that E-11 right now is at the lower end of weapons that even sustain draining fp, unless someone has god-like accuracy or the saberist plays like he doesn't need to conserve fp. I'm not going to address your complaint about ammo, for some weapons it is ridiculously bloated i.e clone rifle; some are totally undersupplied i.e arc's m5. In a pinch M5 just rips off your ammo while you do nerf ball damage with the snipe mode, points well spent.
However ammo is not the direct issue that you are trying to portray as being a reason why saberists suck in your opinion, instead the main error in your example lied in your decision to block and wait until you are out of fp and be vulnerable, because a gunner would struggle more with accurate shooting when the jedi is not blocking but moving.

Regarding the anecdotal evidence of 2 blocking jedi dying to gunners? Heh well nothing to say here at all, except one of my anecdotal evidence of a jedi steamrolling through 5-6 gunners in 3 seconds. An image of blocking jedi dying to gunners doesn't really say much about anything other than their levels of skill.
Why you need to stop being a jedi main immediately: learn other classes for their weaknesses and strengths, you will improve your awareness through learning what their capabilities are and how to respond to their actions.
