hello all, i just started 20 days ago to play again, back from retired (6 months) i just found my crappy account, i bought 3 months of pacc (decide just to not buy much premium) and just own 3 characters on a server non pvp:

1.- paladin lvl 35 70/69
2.-ek lvl 63 77/70
3.-Sorcerer lvl 30 ml 31

i bought some ks, but im a little confused, i was playing elite knight from lvl 30-63 MANUALLY, at first it was exciting, but now it´s just bored :/

about mage, recently lags and kicks on server just stopped any hope to lvl my mage because i just die, and adding plus, that my cnnection normally is bad (playable only at nights) could be painful just lvl mage at midnights, and die on days, spending ks on it...

about paladin, it´s almost same as mage since it need to run all the time, but this has more hp and cap, so it is more like i want to test...

but i just played knight 20 days, if i stopped it will be stupid?? i spent cash lvling up and time, give me some hints please...

or should i just lvl paladin or mage while ek is offline training till he gets skill 100, then going to exp??
give experiences dudes

i just want to reach high lvl in about 2-3 months of manual playing (im not botting right now)

PD: thinking on a license of xenobot just in case, thank you all
