then, I tell you..
Make 2 accounts.
1st play a explorer/voyager till you have full conch ray and make it pure con. (dont full your lightning bolt cuz u're gonna use voyager in sea later on)-(play till lvl 45)
then,
2nd make crus, use your voyager to plvl your crus till lvl 50
after 50 crus can solo and lvl very fast alone.
the voyager can be lvl up later on for sea uses. Maybe you want do fast sea commerce or salvage and max sea skills is good for it.
thats all
