It seems like I have run into an issue.

Hello,
So, I have an Aran, he's about level 133 ( almost 134 ).
No % Str equips, nothing special on him besides the usual (10 att Wg, an avg clean zhelm, like an avg PAC) and an avg PA, i think its about 113 atk or something. He's got about 25 base dex. So, basically, I don't really have funding or anything so its just an average Aran, I'm fine with that, the only problem is I don't have all the skills, for 4th job. I only have the ones that were given during the 4th job advancement. So I got level 10 Overswing, level 10 High Mastery, Level 10 maple warrior, and level 1 Sudden strike. I have about 11 SP points left, which I was saving for Final blow. I've had no luck finding final blow 10 in windia's Fm. Not even on basil. I've saved up about 100mil, most people told me it's worth 150+ mil so ..wow....how come other killer skills of otherclasses are at least cheaper than 100 mil o.o
.Most people recommended me to get overswing 20 instead, or try getting on a zak run and getting the books there. I was thinking that once I get level 10 Final blow my damage would be decent and later one I could just Zak and get the other books(tempest,barrier,high defense, and the other mastery ones) myself.
Training is getting quite slow without Final blow, or better dmg I guess. I usually see other Arans around my level do pretty decent dmg with FB usually over 100k's, plus it looks godly .
Entering a zak run is kind of a hassle for me, I have to do all the prequests and stuff and I haven't zakked before, so I don't really know the 'rules', and I don't know people that would take me on a run, or hell even let me loot the books.
Damage wise the Aran's not too bad, I think he's got 8.5k max atk range clean, it may be horrible for most people, but I'm content, I mean , If I actually spent a lot of time ,money, and energy on this game yeah, it would be something good but, idk I already think its decent, no need to go hungry for power. It just sucks because everyone damage wise does a lot more because they have their skills and they get most of the exp at LHC. It was good back in early lvl 12X's slowly it got bad because everybody else got most of their skills, and dish out optimal damage, I get way less exp relatively speaking. I barely do like 25k~40k dmg with each hit on overswing. While most people pull off twice my dmg at twice the speed. So you see...
So what can I do? , what should I do?
I really don't want to spend money on this game. But if it comes down to it and I have to buy Nx, then well I guess I have no choice, dam Nexon's getting at me here
Thank you for your response, I really appreciate it. I apologize for the bad English.
