Thanks to the cloak skill, you can choose WHEN you want to strike

Make sure you ALWAYS have cure chargers (the green pots). This reduces time that you are debuffed. Cora have this really annoying debuff that stops you from using ANYTHING. (Pots, skills, scroll) the only thing you can buy avalon aron use is the cure charger.

When in maps with other races present, make sure that the last buffs you used are buffs you DONT NEED. Ex (wild rage, extending), to avoid the debuff that removes your buffs from removing a buff that you NEED. Scouts NEED their buffs, quarrel reload especially, quarrel reload = increase attack speed.

When hunting other races, TIMING is essential. Thanks to the cloak skill, you can choose WHEN you want to strike.

When conpt hunting, scouts work better in parties of 2 or 3 times it that you use your skills at the same time and you can kill a level 35+ character before they even know they are being shot at.

Turret is useless in PvP. Cloak is not even that useful in PvP but works well in PvE. I know a few warriors who cross class to striker as well, as it benefit them more for leveling and PvPing.

The key to it all is your play-style, what may work for someone doesn't necessarily mean that it will work for you.
