A few Rogue Questions about Class Levelling etc.

[coffeeortea]

Hello people, I am currently lvl 46 only dagger skills rogue on Phoenix, I've been grinding and getting plevelled hard but I consider myself an extreme newbie. I do not really have any idea what I'm doing and I stopped adding masteries as I'm at 45 now and someone I was talking to online told me to leave a 9 level gap. Now I've read on guides and researched quite abit but I still don't quite understand why I have to do this. Since this is my first char, I don't want to make decisions that I may regret later, and in order to do so, I need to know more about the rogue, but even after reading many guides, I still don't understand what I want.

First off, doesn't this reduce my damage, spells I'm able to learn, basically reduce my potential overall? I know that it increases my sp earned however, but won't I be let's say level 80 but dealing damage of a level 70?

I've been in a huge dilemma deciding what to take as my subclass, this is my first char, and I want this char to be strong and fun. Initially I started out with going for rogue/warlock as it is said to be a good pvp opponent. Everyone else, including my guild is telling me to go either bard or cleric. I do know that with cleric, it is much harder for me to die, and with bard, I don't have to take 10 years to walk to mobs. They say that warlock is a waste because it takes up to much MP. Which I did consider as well.

Regarding my skills, I only have dagger skills now, should I take on a subclass and not max out the essential bow skills? or should i max out the essential bow skills, as well as my subclass skills? Should I just stay pure Rogue?

Thanks for reading this guys, and I would really appreciate help and comments. ^^
