I was going to post this yesterday, but then i discovered it was 1am (GMT) this morning.....anyway, I was going to complain anyway, but if as 0.586 thread claims you are about to do a press push and bring in a bunch of new players then I thinks it's a good idea to do a spell balance pass.
My basic concern is that playing a game with say fireball or forest rage as your basic offensive spell choice is almost like playing a different game to playing with ball lightning, combat is essentially doubled in length and its much easier to get swamped by enemies.
Variety is of course a good thing, but the massive discrepancy in damage output between the basic single target direct damage spells is crazy, Ball Lightning literally does double the DPS of the others.
Now, there are a number of views to take on this.
1) Ball Lightning is horribly overpowered, and fireball et al should be the baseline for the combat experience
2) Fireball et al. are horribly underpowered, and Ball Lightning should be the baseline for the combat experience
3) Fireball et al. are simply there as finishing moves, first shot with ball lightning to do most of the damage, quick second shot with fireball to kill them off (if this is true it needs to be implied somewhere, even to the degree of claiming in the spell description that they are not supposed to be main combat spells)
For the record if you want to look at what i would consider some well balanced spells then Throw Rock, Tidal Pulse and Energy Pulse are all good choices, they have unique benefits that balance out their costs and weaknesses.
Personally I am leaning towards options 2 or 3. If you consciously create a set of spells as finishing moves, then fair enough, as long as each element has an automatically available (which is what stops Throw Rock excusing Forest Rage) Ball Lightning equivalent then it will work quite well. and lets be clear I do just mean equivalent, it just has to have a similar DPS, or other affects that balance it out. The basic requirement is that people aren't gimped for picking the wrong elements, which I'm sure we can all agree with.
EDIT: I added a sentence portion to the last paragraph, noting that other affects can balance out damage.
