4 things to say right now:
1st : I agree with the xMedeia and xclusive. You choose the best build that you think it's suitable with your preferences.
2nd : If you're interested in lvling up fast, choose bower. pacheon/fire/light is just one the fastest lvlers in SRO( i should know, i have 1 on rSRO, it lvls fast even in gap 6-7)
3rd : If you like a slow->medium lvler, choose blader. A friend of mine made a blader here on rSRO. Yes, he does complain that it lvls up hard. BUT... it's a much more rewarding build than the bower.
4th : Idk why, but people that start chars these days..........don't know what to start with,............still, a **** google search wouldn't hurt. And IF googling isn't something you're used to,....1 word:YOUTUBE man!!! YOUTUBE!!!
OK, that's all. I'll stop here.
Keep replying.....or...not
