1.Prayer "When active, aura slowly regenerates the life of you and your party'
I think this aura doesn't make the cut because it isn't a big help when you are in battle, it is useful between battles, but there is a nice thing called life steal which makes you steal your life back in one or two hits. No change here still useless.
2. Resist Fire 'When active, aura damages nearby enemies with heavenly flames'
What is stated above is not true, it does not damages it pumps your fire resist, but why waist an aura on something that only pumps your fire resist. At lvl 20 it gives 131 resist instead of the 75% but waisting that much Points for 1 resist.......
3. Defiance "When active, aura will increase defence rating of you and that of your party"
What I always say: Offence is the best defence, why protect against a monster while you can kill it using damage aura or aura's which make you kill easier, although there can be a variant played called the defiant, but it is a lot harder to level up later on. No changes here.
4. resist cold
same as resist fire, useless in my opinion. Same increase as fire, useless...
5. Cleansing "When active, aura reduces the length of time you and your party will be poisoned or cursed"
Sure poison or curses will reduce your hitpoints but with life steal you can get them back real easy, so this is pretty useless in my opinion. No changes, still useless.
6. resist lightning
same as cold and fire, useless.. Same increase as cold and fire, useless though.
7. Vigor "When active, aura increases stamina recovery rate, maximum stamina and movement speed for you and your party"
Nice skill but you will have to put this one on instead of a damaging skill, although it is sometimes used with charge to achieve immense speeds you gain no damage thus it isn't useful. No changes, same opinion
8. Meditation "When active, aura increases mana recovery rate for you and your party"
Same as prayer, quite useless since you will be having mana steal. Mana recovery rate is doubled but still useless while having mana steal.
9. Redemption "When active, aura redeems the souls of those who are slain to give life and mana to you and your party"
actually another one like meditation or prayer, with mana and life leech this one is irrelevant. No changes.
10. Salvation "when active, aura increases fire,cold and lightning resistance for you and your party"
Quite tempting all your resistance problems solved with one skill but don't forget that this skill only increases resistance and not damage which is very important, I think not necessary, since your damage will suffer. Great increase of 30% here but damage still suffers.
Conclusion about defensive aura's: they are all quite useless except defiance, on my final conclusion I will go deeper in to defiance because it is played as a variant and should be stated as an option for a the funchar. Same as it was although a lot of increase in some skills, pretty useless.
