You know, there are ways to “standardize” a summoner druid run up until the point where you’re just redoing content over and over for drops. A couple of people have posted this over the years but I suppose it helps to post it again.
Generally you want to rush the Edge runeword bow and sell any expensive items/equip any +% gold find items you find, then once you actually assemble Edge (around late normal/early nightmare) you start gambling like crazy until you find a rare weapon with CtC Amplify Damage (preferably a bow for you and your act 1 mercenary). Then you’re all set for Hell. If the blind annoys you, swap Ravens for Dire Wolves.
Obviously if you run Fissure you have other priorities.
The act 2 Might merc was way more useful back when you could only summon the bear, nowadays he tends to gets in the way and the bear/ravens are usually all the damage you need anyway. Feel free to switch to him once you reach your favorite hunting spot or beat the game or find yourself a Reaper’s Toll or whatever, until then the other mercenaries are just more efficient. The act 3 Lightning merc, in particular, is a rising favorite though personally I’d rather have Static Field on something else.
As for snapshot summoning, scaling should have improved the viablity of this for druids somewhat but the bottomline is that a large chunk of druid summon damage is from the CURRENT number of points you have in your Summon Grizzly (softpoints and hardpoints). Druid summoning has always been unique this way, and the upside is that you gain synergy even from just softpoints in Grizzly. Obviously you guys found the downside.
