I mostly play twink hunter in WSG.
Just a few pointers that not everyone knows
1. Train your healing up to 150 then buy the books in the AH (Expert First Aid - Under Wraps) and you can get it up to 225. At 225 you can use (but not make) heavy runecloth bandages and heal to full health up to 2k health in around 3 seconds.
2. Most real twinks know this but the general population doesnt know but you can buy nethercleft or clefthide leg armor and have a lvl 60 install it on your non soulbound armor for +40 stam and 12 agility.
3. most people get the minor speed enchant on their boots, but if you get Nat Pagle's Extreme Anglin' Boots you can get a special enchant called boars speed which has +9 stamina and minor speed.
4. The best headgear is the lucky fishing hat or the green tinted goggles and you can use a libram of constitution to add +100 health to this head item. (for libram you need high lvl to do quesst for you)
5. Another mostly unknown item is the accurate scope which adds +3 to your bow/gun, it must be installed by a lvl 30+
6. one last thing.. you can buy a bundle of 10 rough weight stones or sharpening stones for your blunt or sharp weap to add+2 damage for an hour, this lasts even if you die and they are really inexpensive, around 45silver for a stack
Thats it for now, remember to be super agressive in WSG!!
