1. No its not.
2. Flash until you are out of mana.
3.If you run out of MP fast strike / riot blade -> flash.
Do what I just said and you won't lose agro.
As far as what other people are saying. Yes something about flash scales, I am a very well geared paladin, relic plus 1, valor chest 3 allagan pieces. If you want to test it do a speed run using your relic, it should be fairly smooth. Then run a speed run with a lvl 40 weapon. Watch how you won't be able to hold agro.
