I'm doing 'all the classes to 15' on an alt. It's kinda fun. Rogue is pretty crazy fragile to start, but it gets some stability to it later on. I do all my fate/treasure hunting/dailies/any solo-y stuff on my main with NIN and my healing chocobo (which you can't really get 'til 30 on something). But if you're only taking it to 15, I wouldn't worry too much about it. The consequences for death aren't that huge and as you get more comfortable with the class, you'll probably have an easier time with leves and such.
If you are going to NIN and find you're having a lot of trouble, you could try changing your home point around to whatever's closer to where you're working or lowering the level on the leves you try. If you have the patience for DPS queues, you shouldn't have to worry about low health at all in dungeons/hests and it's sweet exp in there.
In my experience getting to NIN, you're not crazy, ROG is dang squishy when doing things alone. (PUG and LNC can have similar problems without the sturdiness of tankery or backup heals.) I had a few deaths, which isn't something I really experienced with other classes.
PUG to 4 will get you Featherfoot, which is a short duration Evasion buff. Getting it to 8 should get you Second Wind, which is a convenient little heal (long cooldown) to have on your growing ROG. And LNC to 6 will get you Keen Flurry, which is a short duration Parry buff. Cure is always available from CNJ 2, but yeah, your mp will be so low and the strength of the cure will be so sad, it's a hard sell.
