I disagree about pinpoint. Pinpoint is the talent required to make Grenades somewhat viable, but as far as being overpowered? Not really.
Like I said, grenades just aren't all that impressive. The crafting resources to make them are extremely limited, even if you have infinite money. The CCing grenades require essences to make, which are relatively expensive and only sold in very small quantities. The damage grenades require semi-common, but limited (not sold/refreshed) resources, namely empty bottles and nails.
Cost aside, their effects aren't that impressive either. The damage grenades are decent for AoE damage, but still not nearly as good as direct attacks. The CC grenades all have a 50% cc chance or less, and against enemies with any amount of resistence it's extremely likely they won't do anything at all. Compare to arrows with a 100% chance and spells with a 150% chance, it's usually not worth using a grenade, especially after the cost.
I managed to end my last game with over 300 knockdown arrows, 200 stun arrows, 100 charm arrows, and I was selling poison cloud arrows to vendors. I doubt I could have spared even 30 earth essences to make knockdown grenades the entire game.
As for the void dragon, it had 3516hp. I wouldn't go quite that far, as I understand it has some powerful attacks and summons a lot of minions, and you have to protect astarte or lose. It does need enough HP to survive at least 2 rounds of your absolute best, and it should be outright immune to all hard CCs. Slow is fine, but no freeze etc.
In fact, nearly all single-target focused bosses should be hard-CC immune. If you can trivialize the fight with a single spell and a lucky roll, it needs to be changed. That doesn't mean that EVERY boss should be immune, there are plenty that have enough minions that the boss itself is the least of your worry, but something like Boreas, the Trife, and the Void Dragon definitely.
