Two simple advices...
C5 = Fighter chronicle. Imo, create an archer (Personally, I prefer Hawkeye) or any assistant except from PP and SE (sws, bd, bishop, ee, wk,ol, wc).
The other thing you should do is the most important. Join a good clan.
btw it's not worth making your own personal business on low rate. Especially in a server like azure, where dualbox is disabled.
Also, you should not worry about oly if you join a good clan and you are a good person ;)
