Hmmm
I am an Elec / En Blaster, even though I do enjoy my blaster and believe that my dps is good, I certainly notice that my AOE is not up to par.
At lvl 31 I started recording the amount of exp to next level and the amount of exp per even conning npc.
At lvl 31 I needed 314,405 exp and was gaining 143 exp per even con minion, so I needed 2199 (rounding up) minions.
At lvl 32 I needed 386,164 and get 161 per minion = 2399 minions.
At lvl 33 I need 470,416 and get 181 per minion = 2599 minions.
So if I continue to need an extra 200 minions per level up to 40 then my lack of good aoe is going to hurt me even more....
Regarding endurance drain.
In my 33 levels I have never had the endurance drain be effective (even against self resued freakshow that come back with 50% endurance), so as it currently stands the secondary effect of electricity is worthless and makes it by far and away the worst secondary effect of all the blaster lines.
Regarding Thunderous Blast (& possibly Nova?)
At lvl 33 I currently have thunderous blast slotted with 3 damage and 1 recharge, at lvl 34 I will be adding 2 further recharges, the reason for this is that with buildup and aim stacked I can take out a group of red minions, with ball lightning followed by thunderous blast I can take out red minions and orange LT's (my normal targets for these are the elite and field agents in brickstown which come in packs of up to 10). So for me I believe that a faster refresh on thunderous blast is preferable to the extra damage.
I am also unsure about going 5 damage & 1 accuracy on all my attacks, i believe that going 3 damage, 2 recharge and 1 accuracy is more effective (on my lightning bolt / charged bolts) as when stacked with hasten means that they are available most of the time. Given that misses occur against even con mobs even when using aim + with accuracy so's waiting for a power to recycle can and does effect your dps.
