Differences between races:
Dwarf: 10% DoT Resistence, 20% resistance (Knock and Repel)
STR: Damage/DoT resistance/Guard Meter (15~18% All)
Halfling: 10% CC Resistance, 3% Deflect (Final: 15~20% chance deflect).
DEX: Deflection(5~7%%) - AOE resit/Resistance ignored. (15~18%)
Both have Constitution (CON)!
Now what? PvP (Ice Wind and Domination) what would be the most suitable breed?
Note: human is an option, but compared to these two do not see it as being viable and Synergistic!
