Something I've been wondering for a loooong time...

The set bonuses given from enhancement sets. Are these just randomly selected values, or is there a method to the madness?

I can reasonably accept bonuses like 2.5% recovery, but "1.26% Toxic and Psionic resistance" and "3.13 Fire and Cold resistance" and such values like that always makes my mind screech to a halt. Why not a 1.25% or a 1.33% (0.25 being 1/4 and 0.33 being 1/3 of a whole)?

Also, how is it decided which attributes get enhanced? AFAIK Brilliant Leadership is the only set that gives a bonus to both Toxic & Psionic resistances, everywhere else Toxic and Psionic are always enhanced separately.

So, I've combined 3 questions in this thread. Many thanks for the answers! Please let me know if any of these questions need clarification as to exactly what I'm asking.

Wow. Great question, if only for historical understanding. Not sure what use te answer will be, other than try to guess what direction any changes/additions to the I/O system will be.

You are gonna need someone who was up on the thought processes of te Dev team as they were working on this module. Did they publish any of tis anywhere? Is there a guide to the design of the system squirreled away? Did they share these thoughts, was it discussed as it went onto Beta/Live?

I always assumed they used odd numbers because of the rule of 5, and they wanted to be able to add others very similar in bonus. In truth they do not seem to add new sets very often (have they added any?) So maybe the design had more to do with "We want the players to be able to get to X value, but only if they perfectly fit these 12 set bonuses. Or, conversely, we do nt want these 8 set bonuses to make it so "sample archtype" can achieve "undesirable bonus level"

The one that gets me is that the resistance and defense bonuses sound so terribly small but in real game play they are HUGE.

get a new controller to 50 with zero IOs bonuses and everything in the game heads for you first. They pass up tanks to shoot you down.

a good example is me (fresh new 50) joining a SLAM and I land next to a group that's already engaged with a tank and so is the next group over. I got blown up by squishy seeking missiles from the far way group that I wasn't even in range to shot. I didn't even get to shot once and I was dead.

All of the mobs can one shot me and if I do get a cast off I usually have about 10 shooting at me at once.

I really hate playing my ALTS in a SLAM ( nobody does regular LAM anymore ).

With defenses, at least, part of it is also positional and typed bonuses were made to be accompanied by a bonus of the other type of defense equal to half the original bonus.
