Funny, how this discussion runs in circles, Suddenly, we're back to the usual Battle Tactics QQ-ing.
As I've said, I know that there are other skills that are broken and I comment on these issues as well (if someone still didn't notice).
But lets repeat your example, but keep simple this time:
Wizard 1: Lvl 10 Firebolt
Wizard 2: Lvl 10 Lightning Bolt
Who wins?
Now let's remove all cast speed and do it one more time. How is it going to end now?
My statement is that if you want to achieve balance, you have to balance all skills.... and this surely includes assassins and warriors as well. What I suggested here - a vigor / cast speed nerf - would affect any class.
If you nerf vigor, it affect how often a class could use Rage Strike, G-Fist, Aspersio, etc., so it would drop the overall DPS of these classes. CC skills couldn't be cast in a quick succession anymore, so this threat would be gone as well. And the wizard isn't even hurt that much, so it would indirectly be a buff. So if the cast speed of Firebolt and Fireball would be worse, it would only cause a DPS nerf for the Wizard as well.
In the end, it would result in less cc skills and an overall DPS decrease. So it's remarkable that even such a trivial fix doesn't seem to be possible, because "zero cast speed was part of RO1". Wow!
So Battle Tactics is balanced no matter what, because "requires the player to 'waste' statpoints on INT", penetration is balanced because "someone likes it and all stealth classes deserve it" and you can't do anything against DNA bots, because "someone likes to farm them now and then". This game ir really doomed!
i used battle tactic as an example to clearly show that merely comparing single skill damage while neglecting other factors that indirectly effect the skill isnt good.
what is the point of comparing Firebolt no cast speed to Lightning? i thought the issue was mostly Wiz VS other class
off course no cast firebolt would win against Lightning bolt.
Firebolt have the highest skill mod for a 0 CD skill but lack of supplemental skill, makes it so-so
if any of the top tier class have this skill would be godly
even if immobile a BM/monk with firebolt would be fine or atleast make good use of it
Hide + firebolt = relatively easier to re-hide after kill
Battle Tactic + firebolt = 1 dead every 2-3 attack
Wiz + firebolt/ball = are they dominating? there is a reason why wiz pop is dying, the numbers on his kit isnt as strong in game
If you nerf vigor/castspeed
Wiz match up would get worst
Vigor nerf would only benefit Wiz if he could outlived the first set of combos
they arent build to last, prolonged casting of frost driver would make them easier target to Battle Leap for example
Wiz VS others. no match up could get better if cast/vigor is nerfed(nothing comes to mind, right now)
although i agree that other class match up might change ex. priest vs other class
-although i want vigor / cast speed gone so it would be easier to balance class a simple nerf would only make it worst for Wiz
