vit defender can equip strength pendant accessories, melee weapon and other gears to boost melee attack for PA purposes only. If you use gears intended only as supports you will be ****ed anytime in PA.
Yes it is true that you can't support and gain points at the same time...You don't need to support those high DPS Class in PA because they can gain points anytime they want to. Everybody wants 10 pts in PA and will do it by yourself because the DPS class you support will not give it to you the required points you need and make it harder for you because of competition.
Yes there is flaw in my suggestion but it is just simple to minimize the problem in PA, when you add another complicated suggestion it will add another problem too. Gaining points of supports too near the proximity of DPS will raise the problem of ALTS to be abused. EXAMPLE If I have DPS Char and 4 ALTS in our side, of course i will join my 4 alts with my DPS char in PARTY. My 4 alts will eventually gain points easily only just to follow my high DPS character. You solve 1 problem but you add 3 problems this thing should be avoided.
