is that right that ashura champ is weaker compare to agi champ?
nope.
asura champs are stronger because ASURA!!!! 20K Damge [or higher] but i could also suggest agi champs because smart agi champs would bring 4 marina cards so it would freeze and the champ would not have the chance to asura and a smart asura champ would bring marc but they also need phen or bloody butterfly card to continue casting
Agi Champs are more well-rounded than Asura champs... they can hold their own in many situations but can still do a lot of damage.
Asura Champs are one-trick ponies.... in their case, the trick is very, very strong, however. With proper stats/gears, an Asura Champ can get insane damage... I've seen as high as 1.4m in one Asura on Valkyrie Randgris (this is on 99/70 with normal stat caps and gears). If your gears aren't good, then Asura probably won't be that strong.
An "Asura Champ" That these guys are speaking of are really called MVP champs. A pure woe champ(aka spirit) is not a one trick pony. Its tanky enough to survive, does enough asura damage to kill anyone(without ghostring.. but ghostring can be bypassed), can also do very strong and fast occult impact for high def chars, as well as palm push strike for low def. Also can root any dumb char that normal attacks him. Also can snap to get places very fast and to pass traps/precasts...
A spirit champ is one of the most versatile chars in any pvp or woe situation.
