I come with a suggestion to change PVP a bit, which includes towerwars as well.
Mainly I suggest to change the recharge time of all special attacks to 15s, especially aimed shot. Also make it so that in pvp AS requires you to sneak
That would definately change the Overpowered effect of this special and especially would reduce the effectiveness of fixers nowadays
but, for professions that rely on Aimed shot, which is mainly the agent, I suggest giving them the option for burst on their weapon, but ofcours emaking it so that the skill is not dark blue to raise as it would be an IP sink, or at least give them a special attack that doesnt require to be in sneak, but lets face it, Aimed shot is too powerful

Thats at least my opinion, but I'm sure many will dislike my suggestion

EDIT: Same would go for sneak attack ofcourse, but given that its recharge time is already much longer than the Aimed shot recharge, I would suggest reducing the recharge to 15s and making every special cap at that recharge time
