are rogues hard to level and how many keybinds do they use in PVP
Rogues are fairly hard to level IMO compared to other classes. They're quite squishy, especially when fighting multiple mobs (no effective AoE unless your combat (or assass when you have FoK?), which I recommend to play) and you'll be energy starved quite some aswell. I think levels 1 to 70 you'll have a decent easy time due to ambush and eviscerate doing reasonable damage, but 70-90 might be tougher, or at least 80-90.
I actually recently leveled my rogue from 85 to 90 with BoA blues from archaeology and world drops (ilvl 463 dagger, 471 trinket and a 463 mace off-hand). I was playing as sublety, with which it took quite long to kill a monster (15k backstabs on a mob with 200-300k hp) but when I played as assass they went far quicker. I still had to use my defensives frequently and escape frequently.
As for keybinds I think it's the average. If you want to go hardcore keybind mode for PvP, yeah, you'll have quite some binds, but if you're mainly PvEing I think rogues don't have that many binds.
The 85-90 period will be quite a pain, below that it's quite manageable. For pvp, if you want to play sort of seriously, then yes you will need a few keybinds.
How to level rogue with no problems:
1. Spec Assassination
2. Glyph of Deadly Momentum
3. Rupture on every mob right away for energy return when they die
4. Never stop killing
A witty saying proves nothing.
not quite Batman
I died 1 time leveling my rogue from 85-90 and that was because I got cocky and tried to clear an entire area with FoK. It's really not hard. I didn't use Glyph of Deadly Momentum and didn't have food on me. Just use recuperate. Most mobs died with a Mut>Mut>Envenom combo.
I havn't done the grind on a rogue in a long time, however the 2 options to me would be go combat with either crusader or something that icreases your ability to sustain (heals, shields, ect) and barely touch stealth. Option 2 would be assasination multi dotting essentially, rogues have gotten a better leveling toolkit then they used to have when i did mine so i wouldn't say they are the worse class out there.
