Thoughts on the upcoming Issue 24 IO Change.
I immediately thought of Titanium Coating.
Positron's Blast currently gives us +1.58% Fire/Cold Resist, so its maybe not unreasonable to expect under the new system that the three mez resist bonuses become around +2% damage resist to each pair.
3 or 4 sets of those would be nice for any Fire, Elec or Dark Armorer for sure, especially with 2.5% Melee Defence to ice the cake. I'd look at switching my Brute out of Impervium Armor for sure. Nothing hugely transformative, but it could become the new Reactive Armor instead of the set you use for frankenslotting fodder.
Add in 5 of these and an Impervious Skin unique and you could be looking at a good 3-5% res to all six types per power, which would be pretty staggering.
On the other hand, if the devs had added (hypothetically) ranged/E/N def to TOD, that *would* dramatically change how players evaluate the sets. That bonus, added to a set that already has roughly similar bonuses (for 2 more slots) would be attractive to many builds. Looking at the hypothetical from a different angle, if there was a melee set that featured a damage proc and gave a range/E/N DEF bonus for 2 slots, how many builds that currently use KC +2 other slots would not take that 2 slot bonus? The fact that the hypothetical TOD with range/E/N def would also feature a 2.5% damage boost is just gravy.
Obviously if you really needed the extra S/L def or didn't care about other def, or did not plan on using the power and wanted to conserve on slots, KC would still have a lot of things going for it. And, of course, the Devs changed the bonuses to +res, not +def. So this is all hypothetical.
