I hope this will be a PvP game without CC (crowd control) and a resistance caused by a skill. Every MMORPG has shown me the CC balancing makes impossible and games like Aion, the Imunity is also nothing belonging to a PvP game (dodging only manually, not by a skill). Also, skills should have clear constraints. For example, "Protective shield absorbs 100 damage and then ends prematurely." "AoE hits 1-3 enemies" "This skill will cause 30 damage each time the affected character performs a particular action, causing up to 120 Damage and then terminate prematurely ". Videos on Youtube by Guild Wars 1 and Nestlings Farms show what happens when you use skills without damage.
I find abilities that change the character traits for a short time, such as "30% faster running for 30 seconds, 30% slower attack", "15 Seconds for your general armor (which reduces all types of damage) 50% more but you move 50% slower).
In Guld Wars 1, the warrior also had adrenaline (energy generated by suffering and causing damage, except DoT`s, and after the fight, the necromancer had life points as an additional source of energy and got some mana if something And the dervish, a melee who worked with enchantments, got some mana and life when enchantment ended. Enchantment of the class. I hope this will be a combat system where the Character also attacks, if one enters it, and does not even answer "their goal is not within reach", although it is in reach.
