In order to be immune to status effects, go buy a cheap noob shield. Press F4 for Belt 4. Drag noob shield into slot 1. Drag Fire Shield skill into slot 2. Drag primary weapon into slot 3. Leave noob shield on 2nd page of inventory and never remove.
When you are buffing, press F4, then 1, 2, 3 in that order. You will be buffed with fire shield skill, when combined with jewellery at a higher enough lvl can make u immune to every status other than stun. It is fast enough by using the belt system to reload your primary weapon quickly and thereby reducing any slow down to training time.
You cannot job suit/pvp 6x without this skill. Well u can, but you won't be effective. Cuz immune ppl like me can't be frozen or shocked, but if I can freeze u AND knock u down - then I win
Hope this helps
