I have been wearing a set of low TT UL Shogun and hunting Atrax, Merps, etc north of Jason.
My question is this: Is it a worthwhile strategy to not repair my armor to Full TT if I don't want to over-protect myself? I read in the "How Armor Works" thread that Low TT UL armor doesn't protect as much as Full TT UL armor and it also doesn't decay as much when absorbing damage.
It's rare when I disagree with Oleg, but let me suggest that wearing less than fully repaired UL armor
can be used as a good strategy to get the right amount of protection for the lowest decay. I used ~ 2/3 strength goblin quite a bit while sweating snables or kerbs because with full strength goblin I was pretty much always at full health and "wasting" my free natural healing. (Yes, I know sweating naked is a better strategy ped-wise, but I was after concentration skills and was willing to pay a bit for them).
There is a major caveat to this strategy! Each armor has a "minimum decay amount" per hit. This is easy to calculate, as it is .01 pec (.0001 ped) for each point of total protection of any type the armor offers. For ghost, the total protection is 84, so the minimum decay per hit is .84 pecs. Therefore, if I let it decay to a point where the actual protection should cost me .8 pecs, I still pay .84. You can see that as the armor decays more and more this becomes a greater issue. This is also an issue when you take a damage type that the armor protects against just a little. Let a snable spew acid on your ghost, and you will pay .84 pecs for just 1 point of protection. Compare that to the vivo t1 cost of about .1 pec per point of healing, and you can see you are losing out big-time.
For shogun, the total protection = 45, so the minimum decay is .45 pecs. Using full shogun against a young merp, you will get all 1 point hits for a cost of .8 pecs per hit. At 50% condition, you will average 3.3 points of damage per hit at an average cost of .61 pecs per hit. At 40% condition, you take 4.8 average damage for cost of .5 pecs per hit. Your cost/hit bottoms out when the armor is at 36% condition, and at that point to take an average of 5.6 damage/hit. If you let the armor deteriorate beyond this point, you will just get more damage without further reducing your cost, so obviously you want to avoid that.
Since Atrax hit more of shogun's damage types, you can decay your shogun all the way to 24% before you hit the minimum decay of .45 pecs/hit.
So play around with it and see what decay level works for your hunting style while costing you as little as possible. The armor -v- mobs calculator at entropidia.info can be a huge help in sorting out your options.
