Resistance bonuses from sets are lacking as a whole. It's not just any 1 or two damage types.
Pretty much the only ones you'll ever find a decent amount of is Fire/Cold from the purple sets.
There are 4 sets with Energy/Negative:
Tempest (level 15-30 Ranged Damage set at 3slots for 0.63%bonus)
Paralytic (level 10-30 Hold set at 3slots for 0.63%bonus)
Adjusted Targeting (level 21-53 ToHit Buff set at 3slots for 1.26%bonus) and
Shield Wall (level 10-50 PVP Defense Buff set at 4slots for 1.89%bonus)
There are also only 4 sets with Smashing/Lethal:
Air Burst (level 10-53 Target AoE set at 4slots for 0.63%bonus)
Call to Arms (level 10-30 Pet Recharge set at 5slots for 1.89%bonus)
Analyze Weakness 9level 30-53 Accurate Defense Debuff set at 6slots for 1.575%bonus) and
Gladiator's Strike (level 10-50 PVP Melee set at 5slots for 1.89%bonus)
Compared to that there are 14(!) sets with Fire/Cold resist (not going to list them all).
As far as sets with bonuses to a single type:
Smashing has 2 sets it's available on, at 3 and 4slots.
Lethal is only available on Edict of the Master (pet damage set) at 4slots
Fire is only available on Gift of the Ancients at 3slots
Cold has 3 sets at 2 and 3 slots
Energy is only on Detonation (Target AoE) at 3slots
Negative has 6 sets you can get it from at anywhere from 3 to 6 slots required
Psi is available from 10 sets, either for slotting the whole set or as a Special IO
Toxic is likewise available on 16sets as either 6slot bonus or Special IO
For some reason, Despite the widely held view that 1% Defense = 2% Resist; Resist bonuses seem to only be about 1/2 the value of Defense bonuses so you need twice as many harder to get bonuses for the same benefit.
@Oathbound & @Oathbound Too
In general I'd like to see more sets added. Especially to the targeted aoe and I'd like to see temp power recipes become a separate drop. They already interfere with good drops as it is.
Friends don't let friends buy an ncsoft controlled project.
ok here I am complaining about basic fundamental stuff thats missing yet again..
I cannot find a set that gives decent energy and negative resistance as a bonus.
I found 1 set that gives decent def, and one that give some decent negative res..
but in all the sets a tanker could possibly use... no energy res bonus to be found..
grr, and just when i thought I could pump that stat up with the right sets.. I get a big "NO SORRY WE DON'T MAKE THAT"
sooo... maybe we can have a set thats gives nothing but energy and negative energy res global bonuses?
maybe a fully unique melee set where all 5-6 are unique. maybe a purple?
