Can we all please just admit that everything about Vanguard combat mechanics were better than EQ except class balance (at times), animations, and needing some tweaks so energy wasn't quite so unlimited. If we start there, we'll be much fu'ther along than discussing EQ, that I loved, but not for the fucking combat.
I'll start:
Take Vanguards combat, make better animations, have an active dev crew balancing classes a bit better than having no dev crew for years, tweak energy regen dynamics so energy doesn't feel quite so unlimited, call energy mana again, have a 'memorize' function like EQ where you can only have a certain amount of offensive and defensive spells activated at once, make it so you have to sit and 'memorize' a spell like in EQ to change spells and that can cause aggro so you have to be smart, and fucking call energy mana again.
With a dual target system, all buffs group buffs and combined, and the reaction/intercept system.
Fuck the weakness system in the ass.
Done?
