There’s not much of a difference between gold and silver. Try not to focus on your team’s mistake over your own. Your mistakes tend to impact yourself less than your teams as nobody wants to blame themselves.
Personally, I would stay 60 attack and recommend you stick to dscim to dds. Ranging is difficult to learn as a new pker. Try not to ever get smited for the dds and try to keep an eye on who has pid. Hit splats indicate who has pid, if they appear instantly on the hit animiation that means.
