With Etahn, Calculation, Mangler Cannon providing reliable and optional ways to generate crits, I was wondering in what situations, it would be preferable to deal a hit rather than a crit. This is what I was able to come up with so far:
Determination:
Pilot crits are slightly more common than Direct Hits, but there are usually several other desirable crits so this is almost a wash in most cases. The safe money is taking the one damage from the hit and not risking having Determination trigger. However, on Leebo or Chewbacca dealing a normal hit is almost always going to be the best option. Choosing to deal the hit is going to be preferable as well when facing a ship with both Moff Jerjerodd and Determination as you are taking the chance of not dealing any damage if a pilot crit is dealt and your opponent will have the ability to turn any crit they don't like into a regular hit.
Draw Their Fire:
If the target you want to kill is in range of a ship running Draw Their Fire taking the hit instead of the crit is the way to go.
Autoblaster or Autoblaster Turret:
You almost never want to deal a crit with either of these since it is possible for your opponent to cancel crits but not hits.
Salvaged Astromech
Similar to Determination but it will be much more likely to draw a crit that can trigger Salvaged Astromech.
Pilots with abilities that affect the crits they deal (Imperial Kath, Maarek) may make dealing the crit more desirable, but in most cases I can't see their abilities changing things too much. These same considerations will come into play when a ship with Advanced Targeting Computer is deciding whether to burn a Target Lock for a reroll or take the free crit.
