I've been playing for two years and still didn't buy silk.
Never got to a high level either... Level 61 Pacheonmun is my record. Working on my cleric who just hit 42.
Since I'm a trader by nature, and I still enjoy PvPing people of similar levels, it's no big deal for me. Especially now I'm a cleric, I don't even PvP... Just buff around. I only get annoyed when a capped player comes and ruins all the fun (who doesn't get annoyed by someone stronger than you one-hitting you rrepeteadly).
Yesh, Server Traffic often bothers me. But as of lately, I never try to log in during peak hours (which stop somewhere around 18:00 or 6:00pm here) and when I'm being barred by server traffic, I do something else together with trying to log in.
*types password*
*presses Enter*
*didn't connect*
*leave sro, restart it... put a link on windows hotbar*
*do something esle while it loads*
Works perfectly for me, except when I DC and I must get back in quickly. But that doesn't happen much often.
